Description

Technology Field

[0001] The present invention relates to the field of mechanical watch manufacturing.

[0002] More specifically, the present invention relates to a micromechanical operating system having a flexible guide for watch manufacturing. Background Technology

[0003] In the field of micromechanical devices, micromechanical actuation systems are used to transmit motion between two elements of a micromechanical device.

[0004] For example, in the field of watchmaking, push-buttons, levers, or rockers are known to be arranged within a mechanical movement to trigger or operate a specific horological module of a movement, and enable movement or force transmission between two parts of the movement.

[0005] Such an operating system includes an actuator that engages with a part to be operated, which may be a gear wheel or a setting element.

[0006] These actuators typically need to be sufficiently precise for specific applications, and the actuator's displacement must be controlled with great precision.

[0007] Furthermore, to achieve the desired precision and prevent hysteresis, gaps between parts of the actuator must be avoided. More specifically, some operating systems include multiple parts connected by contact.

[0008] Some actuators include a fixed part assembled on a support, e.g., a pivoting part mounted on a plate, and a part movable relative to the fixed part, e.g., a lever pivoting around the pivoting part. To move the movable part while avoiding play between the parts, a spring applies a return force to the movable part to hold it in place or to push it. In the case of a lever, the spring holds the lever in a reference position.

[0009] To displace the lever, the support member pushes the lever from the reference position to the module operating position. When the support member is pulled out, the lever returns to its initial position under the influence of the spring.

[0010] However, for certain functions, these operating systems are not sufficiently accurate and sensitive, particularly for setting up devices that require the actuator to assume multiple precise positions. The problem to be solved

[0011] The objective of the present invention is to overcome some or all of the aforementioned disadvantages by providing a high-precision operating system for a time-side movement. means of solving the problem

[0012] To this end, the present invention relates to an operating system for a time-side movement, wherein the operating system is configured to displace at least partially a portion between a plurality of positions, and the operating system includes a micromechanical actuator intended to engage with said portion, said micromechanical actuator including, for example, a portion intended to be mounted to be held stationary with respect to a plate of the time-side movement, and a portion movable with respect to the fixed portion, said actuator includes a spring portion connecting said movable portion to said fixed portion, said spring portion carrying said movable portion, and the operating system further includes a setting means cooperating with said actuator to displace the movable portion of said actuator between a plurality of positions.

[0013] The present invention is characterized by a spring portion comprising a guide having flexible blades.

[0014] Accordingly, the present invention provides an actuation system having a highly accurate actuator, which can assume a large number of closely spaced positions. Furthermore, the spring portion of the actuation system avoids pole-related occurrences.

[0015] According to a specific embodiment of the present invention, a flexible blade guide comprises at least two translational stages arranged in a row, the first translational stage is connected to a fixed portion, and the last translational stage is connected to a movable portion.

[0016] According to a specific embodiment of the present invention, each translational stage comprises a pair of substantially parallel flexible blades and a rigid section on which the pair of flexible blades are mounted.

[0017] According to a specific embodiment of the present invention, two consecutive translation stages are arranged head-to-tail relative to each other.

[0018] According to a specific embodiment of the present invention, there are an even number of translation stages.

[0019] According to a specific embodiment of the present invention, the rigid sections are extended so that the next translational stage can be associated therewith.

[0020] According to a specific embodiment of the present invention, at least the spring portion is defined as substantially flat so as to be substantially flat. Preferably, this applies to the movable portion as well, or even to the fixed portion.

[0021] According to a specific embodiment of the present invention, at least a second translational stage is arranged on a first side of the first translational stage facing a movable portion with respect to the first translational stage.

[0022] According to a specific embodiment of the present invention, at least the last translation stage is arranged on a second side of the first translation stage facing a movable part.

[0023] According to a specific embodiment of the present invention, a rigid section of a translational stage arranged on a first side furthest from a first translational stage extends to a translational stage arranged on a second side to form a peripheral side of a spring portion.

[0024] According to a specific embodiment of the present invention, each rigid section of the translational stage extends beyond a pair of flexible blades of the translational stage.

[0025] According to a specific embodiment of the present invention, the spring portion is arranged below the fixed portion.

[0026] According to a specific embodiment of the present invention, when the actuator is in a resting position, the flexible blades of the translational stages of the spring portion are substantially parallel.

[0027] According to a specific embodiment of the present invention, the movable part includes a hook.

[0028] According to a specific embodiment of the present invention, the actuator is manufactured as a single piece, and the actuator is obtained using, for example, a LIGA-type or DRIE-type process.

[0029] According to a specific embodiment of the present invention, the movable portion has an elbow shape formed by a first segment arranged perpendicularly to the rigid section of the last translational stage and a second segment forming a right angle with the first segment.

Specific details for implementing the invention

[0033] In the following description, the object of the present invention, which is an operating system, is configured to operate means for controlling the speed of a timepiece adjustment member. However, such an operating system may be used for other applications in time-side movements and is by no means limited to applications in adjustment members.

[0034] FIGS. 1 to 3 schematically illustrate an embodiment of a control member (1) intended to be arranged in a time-side movement comprising a plate (not shown in the drawings) provided with a recess. Such a movement is arranged in a timepiece, for example, a watch.

[0035] The regulating member (1) includes an inertial mass, in this case an annular balance (23), a balance spring (25) as an elastic return element configured to vibrate the inertial mass, a balance staff (24), and a balance bridge (22). These elements are stacked from bottom to top in the order of the balance (23), the balance spring (25), and the balance bridge (22).

[0036] The balance staff (24) passes through the center of the balance, the balance spring (25), and the balance bridge (22). The balance staff (24) is supported by two shock-absorbing bearings (28) arranged at both ends of the balance staff (24). A first bearing is arranged at the bottom of the balance bridge (22), and a second bearing (28) is arranged above it. The balance bridge (22) has a through hole in which the second bearing (28) is supported.

[0037] As illustrated in FIGS. 3 and 4, the balance spring (25) preferably extends substantially in one plane. The balance spring (25) comprises a flexible ribbon (2) that is self-wound multiple times, and the ribbon (2) has a predetermined stiffness. The inner end (9) of the ribbon (2) is integral with or assembled with a rigid support (3), which is commonly referred to as a collet. The rigid support (3) has a substantially triangular shape and is screwed around the staff of the balance (24).

[0038] The balance spring (25) further includes means for adjusting its stiffness. For example, the adjustment means can be operated by the user, particularly when the adjustment member is mounted on the plate of the watch movement.

[0039] The adjustment means preferably includes a flexible element (5) arranged in line with the ribbon (2) as an extension thereof, i.e., arranged following the ribbon, and the flexible element (5) connects the outer end (4) of the ribbon (2) to the rigid support (17). The flexible element (5) is integral with the outer end (4) of the ribbon (2). The flexible element (5) is a different element from the ribbon (2).

[0040] The flexible element (5) adds additional rigidity to the rigidity of the ribbon (2). It is preferable that the flexible element (5) be more rigid than the ribbon (2). In this case, the flexible element (5) is arranged as an extension of the ribbon (2). Preferably, the adjusting means and the ribbon (2) are integrally formed or even made of the same material, for example, silicon.

[0041] The flexible element (5) of the balance spring (25) comprises a first flexible blade (19) and a movable semi-rigid portion (18), the movable semi-rigid portion extending from the outer end of the ribbon (2) and preferably connected to the first flexible blade (19) on the same side of the rigid portion (18). The first flexible blade (19) is also connected to a rigid support (17).

[0042] The rigid support (17) is L-shaped, and the first leg (46) of the L functions as a connection to the first flexible blade (19), and the second leg (47) of the L faces away from the first flexible blade (19) so that it can be assembled to the watch side movement.

[0043] Means for adjusting the balance spring (25) further include a prestressing means (6) that applies a variable force or torque to the flexible element (5). In this way, the stiffness of the balance spring can be adjusted. Due to the prestressing means (6), the torque or force can be continuously adjusted. That is, the torque or force is not limited to isolated values. The stiffness of the flexible element (5) can therefore be adjusted very precisely.

[0044] The prestressing means (6) includes a secondary flexible blade (21) arranged on the opposite side of the rigid portion (18) at the extension of the first flexible blade (19).

[0045] The other end of the secondary flexible blade (21) is connected to a curved lever (14) that runs around the ribbon (2). The lever (14) is connected to a semi-rigid structure (27) attached to a rigid support (17) in addition to the secondary flexible blade (21). The semi-rigid structure (27) is partially deformed when the lever (14) is actuated by force or torque.

[0046] Force or torque is applied to the free end (15) of the lever (14). In this way, the lever (14) of the prestressing means (6) transmits force or torque to the flexible element (5) through the secondary flexible blade (21) and the semi-rigid structure (27), thereby changing the stiffness of the balance spring (25).

[0047] To enable the application of variable force or torque to the balance spring (25), the adjusting member includes a specific operating system (20) according to the present invention.

[0048] The operating system (20) is configured to displace at least partially a portion between multiple positions. In this embodiment, this portion is the lever (14) of the prestressing means (6).

[0049] In the embodiment illustrated in FIGS. 1 to 3, the adjusting member (1) comprises a stud-holder (31) provided with a suspended stud (34). The stud-holder (31) is mechanically connected to the flexible element (5) but does not block the ribbon (2). The stud-holder (31) surrounds the second bearing (28). For this purpose, the stud-holder (31) comprises a center ring (38) arranged around the second bearing (28) and placed on the balance bridge (22).

[0050] The stud (34) works in conjunction with the second leg (47) of the rigid support (17). In this way, the prestressing means (6) and the flexible element (5) are supported by the stud-holder (31) to which they are suspended.

[0051] Additionally, the stud (34) is firmly attached to the rigid support (17). In other words, the stud (34) is integral with the rigid support (17). The stud (34) and the balance spring (25) are assembled by joining, brazing, welding, deformation of metal and glass, or mechanical fastening.

[0052] The stud (34) can move relative to the balance bridge. To do this, the stud-holder (31) can rotate around the second bearing (28) relative to the balance bridge (22). The stud-holder (34) can be displaced over an angular range of, for example, 20° or even 10°.

[0053] By displacing the pin (34) with respect to the balance bridge (22), the bit of the adjustment member (1) can be adjusted.

[0054] The operating system (20) further includes an actuator (30) configured to actuate the lever (14). The actuator (30) is mechanically connected to the prestressing means (6), and the actuator (30) is configured to perform at least partially, preferably substantially, linear, or even straight displacement to actuate the prestressing means (6).

[0055] That is, at least part of the actuator (30) moves substantially along a straight line, unlike the stud-holder (31) which rotates, for example, around an axis. In this way, at least part of the actuator (30) moves toward or away from the balance spring (25) in a direction substantially oriented toward the balance spring.

[0056] Preferably, the displacement direction of the actuator (30) is substantially radial with respect to the balance (23) and the balance spring (25). In this way, the straight line along which the actuator (30) moves is oriented toward the center of the balance spring (25) and the balance (23). This also creates a speed setting independently of the bit setting.

[0057] The actuator (30) is eccentric with respect to the adjustment member, that is, mounted at a distance from the center of the adjustment member (1) and connected only to the lever (14) of the adjustment means. Therefore, the actuator (30) is not mounted directly on the adjustment member (1), for example, a stud-holder on the bearing (28) of the adjustment member (1).

[0058] In this embodiment, the actuator (30) is mounted on the balance bridge (22). Preferably, the actuator (30) is mounted substantially perpendicular to the plane of the balance bridge (22). More specifically, it is assembled at the edge of the balance bridge (22).

[0059] In FIGS. 5 and 6, the actuator (30) comprises a part (33) intended to be mounted to be fixed, for example, to a plate of a watch movement, a part (37) movable to a balance bridge (22) and connected to a lever (14), and a spring part (35) that connects the movable part (37) to the fixed part (33). The fixed part (33) is mounted on the balance bridge (22) in this case and is therefore fixed to it. It is preferable that the fixed part (33) and the movable part (37) be rigid. The fixed part (33), the spring part (35), and the movable part (37) are arranged on the same plane. Thus, the actuator (30) is generally flat and extends substantially in one plane. The actuator (30) is preferably manufactured as a single piece, and the actuator (30) is obtained by, for example, a LIGA-type lithography process or a DRIE-type deep reactive ion etching process.

[0060] To operate the lever (14), the actuator (30) includes a hook (39) that engages with the lever (14), and the hook (39) is mounted on a movable part (37). The hook (39) at least partially surrounds the lever (14), but can also be closed around the lever (14).

[0061] The radial displacement of the movable part (37) of the actuator (30) pulls or pushes the lever (14) radially against the balance spring (25). This changes the stiffness of the flexible element (5) as the displacement of the lever (14) applies a greater or lesser force or torque to the flexible element (5), and consequently, the stiffness of the balance spring (25) changes overall. Thus, the operating system (20) allows the speed of the control member (1) to be controlled.

[0062] Here, the fixed portion (33) has a substantially square shape and is provided with at least one attachment notch (41), preferably two attachment notches (41, 42), for receiving pads (43, 44) extending from the balance bridge (22). The attachment notches (41, 42) are arranged, for example, on two diagonally opposite sides of the fixed portion (33).

[0063] Each notch (41, 42) is provided with a flexible tongue (48, 49) arranged within the notch (41, 42). The first notch (41) is open laterally so as to be able to slide around the first pad (43). The second notch (42) is closed and can accommodate the second pad (44) by insertion into the second notch (42). The flexible tongues (48, 49) deform when the pad (43, 44) enters the notch (41, 42) and act as a support means to hold the pad (43, 44) within the notch (41, 42). Furthermore, the flexible tongues (48, 49) overcome the polarity in positioning the pads (43, 44) within the notches (41, 42), thereby making it possible to improve positioning accuracy, preferably in the same direction.

[0064] As illustrated in the drawings, the actuator (30) is mounted on the balance bridge (22) so as to be substantially perpendicular to the plate and the balance bridge (22). Thus, it is mounted on the edge of the balance bridge (22).

[0065] The spring part (35) is arranged below the fixed part (33) and extends below the level of the balance bridge (22).

[0066] According to the present invention, the spring portion (35) includes a flexible guide. In this case, the flexible guide includes a plurality of translational stages (51, 52, 53, 54) having flexible blades arranged in a row. These are defined as being in a row because the displacements of each translational stage are at least partially accumulated.

[0067] Each translational stage (51, 52, 53, 54) includes a pair of substantially parallel flexible blades (61, 62, 63, 64) and a rigid section (56, 57, 58, 59) on which the pair of flexible blades (61, 62, 63, 64) are mounted.

[0068] The first translational stage (51) is arranged below the fixed part (33) and has a first rigid section (56), which is elongated to be associated with the second translational stage (52) arranged head-to-tail with the first translational stage (51). In this way, the second pair of flexible blades (52) are substantially parallel to the first pair of flexible blades (51). The second rigid section (57) is substantially parallel to the first rigid section (56) but is offset by half the length of the first rigid section.

[0069] The second rigid section (57) is also extended to associate the second translational stage (52) with the third translational stage (53) arranged head-to-tail, and thus is substantially parallel to the first translational stage (51). The third pair of flexible blades (63) are substantially parallel to the first pair of flexible blades (61) and the second pair of flexible blades (62).

[0070] The actuator (30) includes a fourth translation stage (54) arranged on the other side of the first translation stage (5) from the second translation stage (52) and the third translation stage (53). The fourth translation stage (54) is arranged head-to-tail with the third translation stage (53).

[0071] In this way, the fourth pair of flexible blades (64) are substantially parallel to the other pair of flexible blades, and the fourth section (59) is arranged in substantially the same direction as the second section (57).

[0072] The third translation stage (53) and the fourth translation stage (54) are connected by an arm (55) that extends from the third section (58) and passes under the first rigid section (56) of the first translation stage (51).

[0073] The arrangement of these translation stages (51, 52, 53, 54) allows the movable part (37) to be displaced substantially linearly, preferably in a straight line, while maintaining the compact actuator (30).

[0074] Preferably, the actuator (30) includes an even number of translation stages, and two translation stages are arranged head-to-tail so that the vertical deviation of the hook (39) caused by each other can be mutually compensated. In this way, the hook (39) maintains substantially the same height while moving.

[0075] The movable part (37) extends from the fourth section (59). It is preferable that the movable part (37) be rigid. In this case, the movable part (37) has an elbow shape formed by a first segment (66) arranged perpendicularly to the fourth part (59) and a second segment (67) forming a right angle with the first segment (66).

[0076] The hook (39) of the actuator (30) is located at the end of the second segment (67). At the free end of the first segment (66), the bulge (68) acts as a support for moving the movable part (37).

[0077] By applying somewhat strong pressure to the bulging part (68), the movable part (37) moves somewhat closer to the fixed part (33) due to deformation of the translational stages (51, 52, 53, 54) of the spring part (35).

[0078] In this way, the hook (39) is pulled somewhat strongly on the lever (14) to operate the means for adjusting the stiffness of the flexible element (5).

[0079] The displacement direction of the movable part (39) of the actuator (30) and the lever (14) is substantially orthogonal to the direction of the lever (14).

[0080] Furthermore, the lever (14) is preferably movable on the hook (39) so that the lever (14) can slide when performing angular displacement. To this end, the lever (14) includes a free end (15) that cooperates with the hook (39).

[0081] For example, the stud holder (31) must be rotatable so that the bit of the adjustment member (1) can be adjusted. As a result, the balance spring (25) rotates together with the stud holder (31), and the free portion (15) of the lever (14) slides on the hook (39).

[0082] Due to this operating system (20), the bit can be adjusted without the need to modify the position of the actuator (30) specifically with respect to the plate of the movement. The mechanical link between the actuator (30) and the lever (14) is maintained regardless of the position of the lever (14) with respect to the actuator (30).

[0083] Therefore, this operating system (20) allows the speed and beat to be adjusted independently of each other while maintaining a constant predetermined position of the actuator in the movement of, for example, the plate and the balance bridge (22).

[0084] The operating system (20) further includes a control means that cooperates with the actuator (30) to displace the movable part (37) of the actuator (30) between multiple positions.

[0085] As illustrated in FIGS. 7 through 10, the control means comprises a pivotal control lever (45) arranged to displace a movable portion (37) of the actuator (30). The control lever (45) is preferably arranged in a plane substantially perpendicular to the plane of the bulge (68) of the movable portion (37) and comes into contact with it.

[0086] The control lever (45) has a slewing arm (69) and a support arm (71) connected to the hub (72) of the slewing control lever (45).

[0087] The support arm (71) works in conjunction with the movable part (37) of the actuator (30) to mechanically displace it by contact. The support arm (71) pushes the bulge (68) of the movable part (37) more or less to move it. Accordingly, the hook (39) pulls the lever (14) of the balance spring (25) more or less. The control lever (45) is configured to pivot in a plane substantially perpendicular to the plane of the actuator (30).

[0088] The control lever (45) is configured to be mounted on the plate of the movement via a hub (72), which can rotate around a screw body (73), and the screw (73) is mounted on the plate.

[0089] Accordingly, by rotating the control lever (45) around the screw body (73), the spring part (35) of the actuator (30) is deformed to a larger or smaller degree to change the position of the lever (14), so that the movable part (37) moves toward or away from the fixed part (33).

[0090] The control means further includes a control screw (70) mechanically connected to a slewing arm (69) to control the rotation of the control lever (45). The axis of the control screw (70) is arranged within the plane of the control lever (45) in the direction of the slewing arm (69).

[0091] Accordingly, by screwing or unscrewing the control screw (70), the control lever (45) and the actuator (30) are actuated to move the lever (14) of the hook (39) and the prestressing means (6) accordingly.

[0092] The return force of the spring portion (35) of the actuator (30) pushes the control lever (45) against the control screw (70). In this way, the pivot arm (69) of the control lever (45) is held against the control screw (70).

[0093] In FIG. 9, the control screw (70), the control lever (45), the movable part (37) of the actuator (30), and the lever (15) are each in a first position where the hook (39) is lightly pulled on the lever (15). The dashed line shows the control lever (45), the movable part (37) of the actuator (30), and the lever (15) in a second position corresponding to FIG. 10.

[0094] In FIG. 10, the control screw (70), the control lever (45), the movable part (37) of the actuator (30), and the lever (15) are each in a second position where the hook (39) pulls more strongly on the lever (15) than in FIG. 9.

[0095] In the second position, the control screw (70) pushes the pivot arm (69) of the control lever (45), and the support arm (71) in contact with the bulge (68) pushes the movable part (37) of the actuator (30) toward the fixed part (33) by the deformation of the spring part (35). In this way, the hook (39) is pulled on the lever (14), which performs centrifugal displacement.

[0096] In the modified configuration of the spring portion (35), the flexible blades of the first translation stage (51) and the third translation stage (53) are deformed in the same first direction, while the flexible blades of the second translation stage (52) and the fourth translation stage (54) are deformed in the same second direction, which is opposite to the first direction.

[0097] The spring (74) is arranged around the screw body (73) to press the actuator (30) against the balance bridge (22) so as not to separate.

[0098] The spring (74) clamps the screw body (73). The spring (74) is U-shaped and surrounds the screw body (73). One leg of the U extends from the fixed part (33) of the actuator (30) to which it is attached in this case.

[0099] It goes without saying that the present invention is not limited to the embodiments of the adjusting members described in connection with the drawings, and that alternatives may be implemented without departing from the scope of the present invention.
