Detailed Description of the Preferred Embodiments

The invention relates to the field of watchmaking, and more particularly the field of watch movements.

The object of the invention is to provide an autonomous control mechanism 100 complete and arranged to be directly mounted in cooperation with other components or subassemblies constituting a watch movement 1000 or a part of a watch. 2000 watchmaking, including a watch.

This autonomous control mechanism 100 is designed to be entirely assembled apart from the rest of the movement or the piece, and to constitute a versatile module that can be used in different movements or different timepieces.

It is, again, designed to perform control functions of different types, depending on the needs. This description describes more particularly a winding mechanism. The mechanism according to the invention is designed for easy adaptation to other control functions. In a nonlimiting manner, the mechanism 100 can be used for a movement barrel winding control, for a winding drum winding control, for a ringing and / or wakeup selection and triggering control, for a control time zone, or, in general, for the control of other displays than the main display of the movement or the timepiece.

The design of the mechanism 100 is oriented towards a great compactness, in particular as small a thickness as possible, and towards the assembly of all its components on either side of a main bridge 80, with the exception of a rod. control device 10 substantially parallel to the latter, and adapted to be mounted radially or substantially tangentially on the periphery of a timepiece. It is thus possible to equip the periphery of a timepiece, even of small size, with several mechanisms 100 according to the invention, each for the control of one or more particular functions.

This design attaches to easy assembly of the components of the mechanism 100, preferably normally to the main deck 80, which facilitates the automation of the assembly, in particular in a robotic manner, which very significantly reduces the production costs. The components are particularly simple, come from stamping, bar turning or injection, and are themselves inexpensive. The assembly sequence of the components of the mechanism 100 is provided to directly ensure their correct positioning, and their maintenance, which allows any type of manipulation or overturning by a robotic installation without risk of maladjustment or loss of components. The mechanism 100 can thus be assembled finished. The design provides a great ease of assembly and disassembly of the control rod, to facilitate maintenance and after-sales.

Thus, the autonomous control mechanism 100 for a watch movement or a timepiece comprises at least one selection and / or control means, or at least one control rod 10.

The invention is here more particularly described with at least one such selection means and / or control, consisting of a control rod 10. This control rod 10 is movable relative to a main bridge 80 between a plurality of stable positions for pivotally controlling, in each stable rod position, a single control wheel from among a plurality of control wheels which the mechanism 100 comprises. figures 2 , 2A and 3 , 3A illustrate a first recessed position T1 of the rod in a conventional configuration where it is carried in this position winding a barrel; the figures 12 and 14 illustrate a first T2 traction position of the control rod 10, for example for setting a date, and the figures 13 and 15 illustrate a second traction position T3 of the control rod 10, for example for a setting time setting.

Naturally, it is possible to arrange the mechanism 100 with more control positions of the control rod 10: for example, for the mode selection of a striking mechanism, one can provide a position for each mode: small ring , big ring, minute repeater, alarm clock, silence; the associated commands may then consist of wakeup arm / disarm, grand arousal trigger, ringer remount, and the like commands.

In the same way, the control rod 10 is illustrated here with a linear movement in a right longitudinal direction. But a circular motion, or other, is also imaginable without departing from the invention. Naturally, the control rod 10 may also consist of a rack cooperating with a pinion carrying a crown that can be manipulated by the user.

This description and the figures illustrate the preferred case of a single control rod. It is however possible to integrate on the same main bridge 80 several rods or control members, but this particular construction is not detailed here. In particular one can combine on the same main bridge 80 a control rod and a selector, or add a reset command, display spindle, or other.

According to the invention, the control mechanism 100 comprises, on a first side 81, said gear side, the main bridge 80, at least a first control wheel 810 or a first control drive means, for example a cam , a column wheel, a pulley, or the like. The invention is more particularly described in a preferred embodiment, not limiting, including gear transmissions.

The control mechanism 100 further comprises, on a second side 82, said dial side, the main bridge 80 opposite the first side 81, at least one second control wheel 820, or a second control drive means.

The control rod 10 controls the positioning of a pull tab 20. This pull tab 20 is applied to the first side 81, here called "gear side", or on the second side 82, here called "dial side", and is movable in pivoting, by a bore 21 that it comprises, relative to a boss 210 or a pin that includes the main bridge 80, in a stable position of zipper associated with each stable rod position. The invention is illustrated in the figures with the pull tab 20 applied to the first side 81, said to be the gear side, as visible on the figures 2 , 5 , 12 and 13 .

According to the invention, in such a stable pull position, any movement applied to the control rod 10 by the user causes the pivoting movement, or of a single first control train 810 or first control drive means, or a single second control wheel 820 or second control drive means.

The pull tab 20 comprises a flexible arm 24, one free end of which has oblique-tapered teeth, defining recesses called notches 25 or 125 to immobilize it in stable positions of pull relative to a boss 250 or a pin that the bridge comprises. main 80. In a preferred embodiment, the boss 250 is extended by a washer 251, driven and / or welded thereto, which provides the holding function of the elastic arm 24. Thus, the arm 24 is bent on the washer 251 when lifting the pull arm 22.

The Figure 2A and the figure 5 show notches 25A, 25B, 25C, adapted for holding the pull tab for the depressed T1 position of the control rod 10 in the case of the figure 2 where the notch 25A cooperates with a pin 250 driven on the main deck 80, for the first position T2 pulled from the control rod 10 in the case of the figure 12 corresponding also to the figure 14 and where the notch 25B cooperates with the pin 250, and for the second position T3 pulled from the control rod 10 in the case of the figure 13 corresponding also to the figure 15 and where the notch 25C cooperates with the pin 250. This notch 25C is, in this particular case, constituted only by a slope at the end of the flexible arm 24.

The pull tab 20 further comprises an oblong slot 26, arranged to cooperate, in a position of plating of the pull tab 20, with a boss 260 or a pin 126 that includes the main bridge 80.

The control rod 10 conventionally comprises guide means, such as a square-section shaft or the like, which cooperate with complementary guide means, such as a female square, or dishes, or the like, which comprises a pinion runner 13 mounted on the control rod 10, so as to allow a translation of the sliding pinion 13 relative to the control rod 10 in a longitudinal direction in which the control rod 10 is movable relative to the main bridge 80, and so as to slave the sliding pinion 13 pivotally with the control rod 10 relative to a pivot axis about which the control rod 10 is arranged to rotate.

The figure 18 illustrates a pull tab 20, an outer side of the flexible arm 24 has notches 125A, 125B, 125C, which are disposed opposite the pivot boss 210 housed in the bore 21 of the pull tab 20, while in the variant of the figure 5 the notches 25A, 25B, 25C are disposed on the inner side of the arm 24 facing this pivot. This figure 18 corresponds to the depressed position T1 of the control rod 10, where the notch 125A cooperates with the pin 250 to ensure by itself the maintenance in this position 1. And the pin 126 integral with the plate is then distant from the edge of the light 26 a short distance d. In case of shock, in particular on the rod, this shock causes the pull tab 20, and is absorbed by the deformation of the flexible arm 24 forming spring, and the light 26 acts as a stroke limiter. The displacement of a sliding pinion 13 is taken up by an almond bearing that comprises a stepped pin 64 which will be presented later.

As visible on the figures 2 and 3 , the sliding pinion 13 further comprises a first drive means 14, which is arranged to drive a first control wheel 810, or first control drive means. The sliding pinion 13 further comprises a second drive means 15 arranged to drive a second control wheel 820, or second control drive means.

The control rod 10 has a groove 11, as visible on the figure 3 , arranged to drive a first arm 22 that includes the pull tab 20, to bring it from one stable position of pull to another. The control rod 10 comprises a rod lock 19, for example in the form of a shoulder, which limits on one side the groove 11, and the support of the first pull arm 22 prohibits the extraction of the rod from command 10 in normal regime; according to the invention, the only possibility of extraction of the control rod 10, as will be explained later, is to act on the elasticity of this pull arm 22, and deform it away from the axis of the control rod 10 to allow the release thereof.

The pull tab 20 further comprises a second arm 23, which is arranged to cooperate with a groove 16 that includes the sliding pinion 13 visible on the figure 14 , to move the sliding pinion 13 between a first position where the first drive means 14 cooperates with a first control gear 810 or first control drive means, and a second position where the second drive means 15 cooperates with a second control wheel 820 or second control drive means. In the first position of the sliding pinion 13, the second drive means 15 does not does not cooperate with a second control wheel 820 or second control drive means, and in the second position of the sliding gear 13 the first drive means 14 does not cooperate with a first control gear 810 or first means of control. command drive

In a preferred embodiment of the invention, as visible in the figures, the sliding pinion 13 is in one piece, and has a first toothing 14 arranged to cooperate with a first idler wheel 63, called a crown gear, for driving such a gear. first control train 810 or first control drive means. The sliding pinion 13 comprises, in the same way, and at the opposite end of the first toothing 14, a second toothing 15 arranged to cooperate with a second idler wheel 36 driving a second control wheel 820 or second means command drive.

The first idler wheel 63 and the second idler wheel 36 are located on two opposite sides of the main deck 80, in the thickness of which the control rod 10 and the sliding pinion 13 circulate. It is therefore clear that the sliding pinion 13 engages only with one of these two crazy wheels at a time. The meshing with each of the wheels is on two opposite sides of the main deck 80, with two opposite sets of teeth 14 and 15 of the sliding pinion 13. In the embodiment illustrated in the figures, the first idler wheel 63 can mesh with the first toothing 14 of the sliding pinion 13, the first side 81, said gear side, of the main bridge 80, as visible on the figures 2 and 4 . While the second idler wheel 36 can mesh with the second toothing 15 of the sliding pinion 13, the second side 82, said dial side, of the main bridge 80, as visible on the figure 11 .

Preferably, as visible on the figure 11 , the first toothing 14 of the sliding pinion 13 is of larger diameter than the second toothing 15, their radius deviation is slightly greater than the thickness of the first idler wheel 63, so that the latter can pass through above the second toothing 15 of the sliding pinion 13 when the control rod 10 is in one of the traction positions T2 or T3

This sliding pinion 13 can be executed by injection, metal, or high-strength plastic material.

The design is simplified compared to the usual winding mechanisms, no Breguet toothing is needed here, which reduces the cost of the assembly.

Preferably, the main bridge 80, designed to be an injected part, in particular plastic, supports the maximum complexity, so that all other components are as simple as possible. This main bridge 80 has tenons or bosses of recovery of effort relative to a plate on which it is arranged to be assembled.

The wheels and movable members pivoting relative to the main bridge 80 are preferably pivotally mounted on steel pivots, which are driven into this main bridge 80.

The main deck 80 preferably comprises a cylindrical cradle 83 for receiving a cylindrical bearing surface of the sliding pinion 13.

This cradle 83 also comprises a bore 84 serving as a housing for a stepped post 64 whose function will be detailed later.

The autonomous control mechanism 100 comprises, applied on the first side 81 or the second side 82 of the main bridge 80 opposite the one carrying the pull tab 20, a latch 30, shown in FIG. figure 6 . This rocker 30 is arranged to carry a second idler wheel 36 arranged to cooperate with the second drive means 15, for driving, according to the position of the rocker 30, a single second control wheel 820 or second means d control drive, among a plurality of second control wheels 820 or second control drive means.

The rocker 30 is pivotally mounted, at a bore 31 that it comprises, on a boss 310 or a pin that includes the main bridge 80. The rocker 30 is pivoted under the effect of the displacement of the rod. control 10 in the longitudinal direction, directly or indirectly via the sliding pinion 13.

As visible on the figure 9 , the latch 30 comprises an oblong slot 33, which cooperates with a stud 330 of the main bridge 80, which constitutes a travel limiter of the latch 30.

The rocker 30 comprises a pivot supporting the second idler wheel 36, this pivot is preferably in the form of a stepped pin 32, a flange of which serves to maintain the recommended intermeshing distances with a first wheel 46 and with a second wheel 47, with which can alternately cooperate the second idler wheel 36. This pin 32 can be made by bar turning, it can also come deep drawing with the latch 30 itself.

In the particular embodiment illustrated in the figures, the main bridge 80 carries a first boss 460 or pivot, which is arranged to pivotally guide a first wheel 46 that includes one of the second control wheels 820 or second control drive means. This first wheel 46 is arranged to mesh with the second idler wheel 36 in a first position of the rocker 30.

The main bridge 80 carries a second boss 470 or pivot, which is arranged to pivotally guide a second wheel 47 that includes one of the second control wheels 820 or second control drive means. This second wheel 46 is arranged to mesh with the second idler wheel 36 in a second position of the rocker 30. The rocker 30 is interposed between the main bridge 80 and the first wheel 46 on the one hand, and the second wheel 47 of somewhere else.

The invention is illustrated for a particular embodiment where the first wheel 46 controls the time setting of the movement 1000, and where the second wheel 47 controls the adjustment of the date.

The rocker 30 comprises an elastic arm 34, a free end of which has bearing surfaces 35 which are arranged to cooperate in the locking position with a boss 420 or a pin that comprises the main bridge 80. figures 6 , 14 and 15 illustrate these bearing surfaces 35A and 35B, and their cooperation with a boss or a pin 420 that includes the main bridge 80. On the figure 14 in a first pulled position T2 of the control rod 10, the rocker 30 is driven so that the bearing surface 35B bears on the boss 420, the rocker 30 is then pivoted into a position where the second idle wheel 36 meshes with the second wheel 47 to perform a date adjustment. On the figure 15 , in a second drawn position T3 of the 10, the rocker 30 is driven so that the bearing surface 35A is supported on the boss 420, the rocker 30 is then pivoted in a position where the second idler wheel 36 meshes with the first wheel 46 to perform a time setting.

The autonomous control mechanism 100 comprises a secondary bridge 40, which is arranged to cover the first wheel 46 and the second wheel 47, on the opposite side to the rocker 30. This secondary bridge 40 is driven and / or welded, at the level of a bore 42 that it comprises, on a boss 420 or pin of the main bridge 80 on the one hand It is still fixed, here at a lug 41 that includes, in particular welded on a boss 310 or pin of the bridge main 80, in a variant it may also include in this tab 41 a bore removed and / or welded on the boss 310 or pin.

Each in turn cooperates in bearing with the bore 63A of the first idler wheel 63. The disengagement function provided by this almond profile avoids any tooth-to-tooth interference contact in the traction position of the control rod. 10.

As visible on the figure 2 , the main bridge 80 carries a second boss 610 or pivot arranged to guide pivotally, by a bore 62, a return wheel 61 meshing with the first idler wheel 63, and plated on the main deck 80. This idler wheel 61 is in particular a ratchet driver for winding a barrel, not shown in the figures.

The autonomous control mechanism 100 includes a pull tab holder 50, shown in FIG. figure 8 and visible on the figures 2 and 11 . This pull tab holder 50 is arranged to cover the first idler wheel 63 and the idler wheel 61, superimposed on the pull tab 20 which is mounted captive between the main bridge 80 and the pull tab holder 50: maintenance pull tab 50 may comprise, in a manner not shown in the figures, a bore, or an oblong, or the like arranged to cooperate in alignment with a bearing of this stepped stud 64, so as to constitute a mounting aid, which can help also be performed optically, including using a camera. The pull tab 50 is preferably driven out and / or welded to the boss 210 or pin at a bore 52, and at the boss 610 or pin at a bore 51.

The pull tab holder 50 includes a first jumper arm 56 arranged to push the first idler wheel 63 and mesh with the first drive means 14. This jumper arm 56 is of sufficient length to prevent any jamming a tooth of the first idler wheel 63 on its free end. In another variant, not shown in the figures, this jumper arm has no free end, and is constituted by an arm of small section, held at both ends, of the pull tab holder 50. alternatively, the first jumper arm 56 may be attached, in particular by welding, to the puller retaining plate 50. This first jumper 56 avoids any risk of tooth-to-tooth contact during retraction of the rod into its depressed position T1. corresponding here to reassembly. The distance of the toothing is achieved by the choice of teeth of different diameters for the first toothing 14 and for the second toothing 15 of the sliding pinion 13.

The puller holding plate 50 comprises a second jumper arm 57, which is arranged to push back towards the main bridge 80 a first arm 22, which comprises the pull tab 20, to cooperate with a groove 11 of the control rod 10, so as to to maintain the height of the pull tab 20 relative to the main bridge 80, and to maintain the control rod 10 in one of the stable rod positions. This second jumper 57 thus ensures the height of the zipper 20 is maintained, and keeps the control rod 10 in the locked position, regardless of the position of the watch. This holding in position is assured whatever the position of this mechanism 100 or a movement 1000 in which the mechanism 100 is integrated, or a timepiece 2000 in which the mechanism 100 is integrated.

In an alternative embodiment to the maintenance of the flexible arm 24 of the pull tab 20 by a washer 251, as explained above, the puller holding plate 50 may also comprise substantially in the extension of a first arm carrying the bore 52 and the second jumper 57, a support arm arranged to push back to the main bridge 80 this flexible arm 24 to ensure contact between the notches 25 on the one hand, and the boss 250 or pin on the other hand.

Like the secondary bridge 40, the pull tab holder 50 is provided to be fixed by welding, in particular by laser welding, on the boss 610 or pin on the one hand, and on the pivot boss 210 of the pull tab 20. 'somewhere else. This secondary bridge 40 and this pull tab holder 50 are preferably stepped plates having inclined faces, obtained by stamping. The folding of these components 40 and 50 during gives an elasticity on which it is possible to play during their assembly, and to achieve a prestressing.

Advantageously, to facilitate the assembly and disassembly of the control rod 10, the main bridge 80 comprises a housing 73 for receiving a lever 70. This lever 70 comprises an operating arm 71 arranged to receive pressure from a user and away from this main bridge 80 a support arm 72 arranged to move away from this main bridge 80 a free end of the first arm 22 of the pull tab 20. The main bridge 80 has a slot 75 for the insertion of this lever 70, which is substantially flat, perpendicular to one of the sides 81 or 82 of the main bridge 80, one end of this lever has hinged projections. This configuration allows insertion and tilting with a robot gripper. Once tilted, the lever 70 is retained, in the direction of the thickness of the main bridge 80, by the pull tab 20, and is held in the other directions by the housing 73 of the main bridge 80, which is complementary to its profile . A fulcrum 74 makes it possible to carry out the support required to tilt the lever 70, to lift the pull tab 20 away from the axis of the control rod 10, and thus to release the latter.

In this mechanism 100, the toothing modules are chosen as wide as possible, so as to improve the resistance of the teeth to the service constraints. The use of pivots of fairly large diameters makes it possible to reduce the Hertz pressure and to improve the wear behavior of the modules. The design allows the use of stamped teeth, which is particularly economical.

The embodiment is illustrated here with a substantially flat main bridge 80, with two substantially parallel faces. It is understood that the invention is generalizable to any form of main bridge or frame, on which there are components on different faces, these components cooperating alternately with a control member disposed between these support faces. It is for example conceivable to make the main bridge 80 in the form of a cube, a sphere, or other.

The various centering bosses or pivots can be made in one piece with the main bridge 80, instead of being reported on him.

The assembly of the components is normally feasible on each side, in a mounting sequence which ensures the maintenance, at each intermediate stage, of the components already mounted, so as to allow any movement in space with robotic handling equipment.
