Description

Technical Field

[0001] The invention relates to a flexible guide with a translation stage for a rotary resonator mechanism, in particular for a timepiece movement. The invention further relates to a rotary resonator mechanism provided with such a flexible guide. Background Art

[0002] Most mechanical watches today are equipped with a balance spring and a Swiss escapement. The balance spring forms the time base of the watch. It is also called a resonator.

[0003] The escapement has two main functions:

[0004] - Keep the resonator moving back and forth;

[0005] - Count these back and forth movements.

[0006] An inertial element, a guide and an elastic return element are required in order to constitute a mechanical resonator. Conventionally, a spiral hairspring acts as an elastic return element for the inertial element constituted by the balance wheel. The balance wheel is guided in rotation by a pivot rotating inside a common ruby ​​bearing. This causes friction and therefore energy losses and operating disturbances, which are position-dependent and should ideally be eliminated.

[0007] Flexible guides are currently used as balance springs to form virtual pivots. Virtual pivot flexible guides allow a considerable improvement of timepiece resonators. The simplest of them are cross-blade pivots, which consist of two guides with straight blades that usually cross each other at right angles. The two blades can be three-dimensional in two different planes or two-dimensional in the same plane and thus act like a weld at the intersection between them.

[0008] However, when it is desired to use a flexible blade to pivot the rotating annular balance in a manner similar to the movement of a balance with a balance spring, isochronous motion cannot be obtained. More specifically, a perfectly periodic rotational motion of the pendulum cannot be obtained. The return torque is nonlinear, which results in non-isochronisms that vary with the amplitude of the displacement of the pendulum and with the rate of the movement. Moreover, the axis of rotation of these resonators is not fixed, but moves with the rotation of the balance. This disturbing motion is small, however, it affects the rate of the movement due to the change in the orientation of the watch relative to gravity. Summary of the invention

[0009] It is therefore an object of the present invention to propose a flexible guide for a rotary resonator mechanism which does not suffer from the above mentioned problems.

[0010] To this end, the invention relates to a flexible guide for a rotating resonator mechanism, in particular for a watch movement, comprising: a fixed support; a movable element movable relative to the fixed support; and at least one main flexible blade, allowing the movable element to be moved relative to the fixed support via a rotational movement around a center of rotation by bending one or more main flexible blades, the flexible guide being substantially arranged in one plane.

[0011] It is worth noting that the flexible guide comprises at least one translation stage connected to one end of the main flexible blade, the main flexible blade and the translation stage being arranged in series and forming a pair connected to a fixed support, a movable element or an intermediate movable part, so that the translation stage is configured to move translationally at least partially under the influence of the bending of the main flexible blade.

[0012] The invention thus provides an isochronous flexible blade guide. More specifically, the translation stage allows the main blade to move as it bends, thus maintaining a substantially constant coefficient of return. The movement of the balance wheel is thus isochronous. Such a flexible guide ensures isochronous movement.

[0013] According to an advantageous embodiment, the guide comprises at least three pairs, for example four, each pair formed by a main blade and a translation stage, the pairs being angularly distributed so as to form a symmetrical pivot, each main blade being linked at one end to the translation stage.

[0014] According to an advantageous embodiment, the translation stage is arranged in series between the fixed support and said primary flexible blade, the translation stage being linked to the fixed support and to a first end of the primary flexible blade, which is linked at a second end to the movable element.

[0015] According to an advantageous embodiment, a translation stage is arranged in series between said primary flexible blade and the movable element, the translation stage being linked to the movable element and to the second end of the primary flexible blade, the primary flexible blade being linked at a first end to the fixed support.

[0016] According to an advantageous embodiment, the guide comprises at least six pairs, preferably eight pairs, each pair consisting of a main blade and a translation stage, the pairs being angularly distributed around a central portion so as to form a symmetrical pivot, each main blade being linked to the central portion at one end, at least three pairs being linked to a fixed support and at least three pairs being linked to the movable element via a translation stage.

[0017] According to an advantageous embodiment, the pairs linked to the fixed support and the pairs linked to the movable element are distributed alternately around the central portion.

[0018] According to an advantageous embodiment, the movable element comprises a central portion of the guide, to which central portion the main flexible blade is attached.

[0019] According to an advantageous embodiment, the fixed support comprises a central portion of the guide to which the main flexible blade is attached.

[0020] According to an advantageous embodiment, the guide comprises a central portion forming an intermediate element between the support and the movable element, to which central portion the main flexible blade is attached.

[0021] According to an advantageous embodiment, the translation stage comprises at least one secondary flexible blade and a rigid part, the secondary flexible blade being linked at one end to the rigid part and at the other end to a fixed support, a movable element or a central part.

[0022] According to an advantageous embodiment, the translation stage comprises two secondary flexible blades joined to the same face of the rigid part.

[0023] According to an advantageous embodiment, the translation stage comprises at least two secondary flexible blades which are linked at one end to the main flexible blade and at the other end to the fixed support, the movable element or the central part.

[0024] According to an advantageous embodiment, the secondary flexible blades are arranged in different rows.

[0025] According to an advantageous embodiment, the secondary flexible blades are substantially parallel.

[0026] According to an advantageous embodiment, the rigid portion forms a bend such that, when the guide is in the rest position, the one or more primary flexible blades are substantially perpendicular to the one or more secondary flexible blades of the translation stage coupled to the primary flexible blades.

[0027] According to an advantageous embodiment, the movable element comprises a balance wheel, for example centred on the central portion.

[0028] According to an advantageous embodiment, each translation stage is connected to only one main flexible blade.

[0029] According to an advantageous embodiment, a pair is connected to only two different parts among the fixed support, the movable element and the intermediate movable part.

[0030] The invention further relates to a rotating resonator mechanism, in particular for a timepiece movement, comprising a flexible guide according to the invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Figures 1 to 3A first embodiment of a flexible guide 1 for a rotating resonator mechanism, in particular for a watch movement, is shown. The flexible guide 1 is arranged substantially in one plane. The flexible guide comprises: a fixed support 2; a movable element 20 movable relative to the fixed support 2; and three main flexible blades 3, 4, 5, each connecting the movable element 20 to the support 2. The main flexible blades 3, 4, 5 allow the movable element 20 to be moved relative to the fixed support 2. By bending the main flexible blades 3, 4, 5, the movable element 20 can be moved relative to the support 2 around a center of rotation with a rotational movement about itself. The main blades 3, 4, 5 preferably have the same length and are evenly angularly distributed around a central portion 6 of the movable element 20 so as to form a symmetrical pivot.

[0047] According to the invention, the flexible guide 1 comprises a translation stage 10, 11, 12, each of which is connected to one end of a different primary flexible blade 3, 4, 5. In this embodiment, the translation stages 10, 11, 12 are arranged in series between the fixed support 2 and the corresponding primary flexible blade 3, 4, 5. The translation stages 10, 11, 12 are connected to the fixed support 2 and to a first end of the corresponding primary flexible blade 3, 4, 5, which is connected to the central part 6 by a second end. Each translation stage 10, 11, 12 is arranged in series with a different primary flexible blade 3, 4, 5. The translation stages 10, 11, 12 are connected to a single primary flexible blade 3, 4, 5.

[0048] Thus, the flexible guide 1 comprises three pairs, each pair consisting of a main flexible blade 3, 4, 5 and a translation stage 10, 11, 12. The pairs are angularly distributed around a central portion 6 so as to form a symmetrical pivot, each main blade 3, 4, 5 being linked at one end to the central portion 6, and the translation stage 10, 11, 12 being linked to the fixed support 2. The pairs, in particular the main blades 3, 4, 5, form an angle of about 120° with each other. The central portion 6 is, for example, a section of a cylinder. In this embodiment, the movable element 20 comprises the central portion 6.

[0049] Each translation stage 10, 11, 12 is configured to move in translation at least partially under the influence of the movement of the main flexible blade 3, 4, 5. Each translation stage 10, 11, 12 comprises at least one secondary flexible blade 7, 8, 9 (in this case two secondary flexible blades 7, 8, 9) and a rigid part 13, 14, 15. The secondary flexible blades 7, 8, 9 are attached at one end to the rigid part 13, 14, 15 and at the other end to the fixed support 2. The secondary flexible blades 7, 8, 9 are substantially parallel and arranged in different rows. Preferably, the secondary flexible blades 7, 8, 9 are attached to the same face of the rigid part 13, 14, 15. In this case, the rigid part 13, 14, 15 forms a right-angle bend comprising two substantially perpendicular sections. The main flexible blade 3, 4, 5 is attached to the first section, while the secondary blade 7, 8, 9 is attached to the second section. Thus, when the guide 1 is in the rest position, the primary flexible blades 3, 4, 5 are substantially perpendicular to the secondary flexible blades 7, 8, 9 of the translation stages 10, 11, 12. The rest position is defined as the position when the primary blades 3, 4, 5 and the secondary blades 7, 8, 9 are straight (i.e. not bent).

[0050] exist Figure 2 In the embodiment of the invention, the movable element 20 further comprises a balance wheel 16, which is annular. The balance wheel 16 comprises an outer annular portion 17 and arms 18 (three arms in this case) which connect the annular portion 17 to a connection point 19 axially to the annular portion 17. The arms 18 are concentric and of equal length. The balance wheel 16 is assembled on the central portion 6 via the connection point 19. Preferably, the central portion 6 and the connection point 19 are made in one piece. Thus, the balance wheel 16 is centered relative to the central portion 6. In this alternative embodiment, the balance wheel is made of the same material, i.e. it is made in one piece.

[0051] When the balance wheel 16 is in motion, it follows a periodic rotational motion in the plane of the balance wheel 16, in one direction and then in the other direction, about an axis passing through the connection point 19 and the central part 6. The main flexible blades 3, 4, 5 bend and act as return springs for the balance wheel 16 to rotate it in the other direction and vice versa. The translation stages 10, 11, 12 allow the main blades 3, 4, 5 to move longitudinally when they bend. The rigid parts 13, 14, 15 of the translation stages 10, 11, 12 move towards the central part 6 with the help of the secondary blades 7, 8, 9 when the main blades 3, 4, 5 bend, and move away from the central part 6 when the main blades 3, 4, 5 straighten. This ensures that the movement of the balance wheel 16 remains isochronous.

[0052] exist Figure 3In the second alternative flexible guide 26 of the first embodiment of the invention, the movable element 20 comprises at least two components. The first component 21 comprises arms 22 (three arms in this case) and axial connection points 25, which are made in one piece. The arms 22 are equipped at their free ends with attachment platforms 23, which are provided with holes 24 for assembling an inertial element (such as an inertial block or ring) which defines the second component of the balance wheel 20 and at Figure 3 The other parts of the flexible guide 26 are the same as in the first alternative embodiment. Preferably, the central part 6 and the first member 21 are made in one piece.

[0053] Figure 4 The second embodiment in FIG. 1 shows an example of a flexible guide 30 in which a translation stage 33, 34, 35 is attached to a movable element 32, which preferably has an annular shape. The flexible guide 30 comprises a fixed support 31, a movable element 32, and three pairs consisting of main flexible blades 36, 37, 38 and translation stages 33, 34, 35. Each translation stage 33, 34, 35 is arranged in series between the main flexible blades 36, 37, 38 and the movable element 32. Each main flexible blade 36, 37, 38 is attached to the fixed support 31 at a first end. The translation stages 33, 34, 35 are attached to the annular portion of the movable element 32 and the second ends of the main flexible blades 36, 37, 38. In this embodiment, the fixed support 31 comprises a central portion to which the first ends of the main flexible blades 36, 37, 38 are attached. The central portion also takes the shape of a cylindrical portion and is preferably circular. Preferably, the movable element 32 comprises three inner extensions 39 oriented in a plane towards the inside of the ring to allow the assembly of the secondary flexible blades 27, 28, 29 of each translation stage 33, 34, 35. The secondary flexible blades 27, 28, 29 are substantially parallel and arranged in different rows. Preferably, the secondary flexible blades 27, 28, 29 are attached to the same face of the rigid part. When in the rest position, the extensions 39 extend in a direction substantially perpendicular to the direction of the primary flexible blades 36, 37, 38, so that the secondary flexible blades 27, 28, 29 are guided along this way. Therefore, the secondary flexible blades 27, 28, 29 are substantially perpendicular to the direction of the primary flexible blades 36, 37, 38. In this embodiment, the translation stages 33, 34, 35 are not attached directly to the fixed support 31, but to the movable element 32. The effects obtained are the same as in the first embodiment, in particular with regard to the isochronism of the movement of the balance wheel 32.

[0054] Figure 5 and Figure 6The third embodiment of the flexible guide 40 in is similar to the first embodiment, but in addition to the movable element 50 and the fixed support 52, it also includes four pairs consisting of translation stages 46, 47, 48, 49 and main flexible blades 42, 43, 44, 45. These four pairs allow the guide to be symmetrical every 90°, especially in line with the properties of anisotropic materials that can be used to manufacture the guide. The properties of the material change periodically depending on the orientation, for example silicon changes every 90°. These pairs are angularly distributed around the central part 51 of the movable element 50 to form a symmetry pivot. These pairs (especially the main flexible blades 42, 43, 44, 45) form a substantially perpendicular angle of about 90° with each other. As seen in the first embodiment, the four translation stages 46, 47, 48, 49 are each arranged between the main flexible blades 42, 43, 44, 45 and the fixed support 52. Each main flexible blade 42, 43, 44, 45 is linked at one end to a translation stage 46, 47, 48, 49 and at the other end to a central part 51. The movable element 50 comprises a preferably annular balance 53 equipped with four arms 54 linked at an axial connection point 55. Preferably, the central part 51, the connection point 55, the annular part 53 and the arms 54 are made in one piece.

[0055] Figure 7 and Figure 8 A fourth embodiment of a flexible guide 60 is shown, comprising eight pairs, each pair being formed in series by a main flexible blade 61, 63, 64, 65, 66, 67, 68, 69 and a translation stage. These pairs 71-61, 72-63, 73-64, 74-65, 75-66, 76-67, 77-68, 78-69 are distributed angularly around the central part 59 so as to form a symmetrical pivot. Each main flexible blade 61, 63, 64, 65, 66, 67, 68, 69 is linked to the central part 59 at one end. Four pairs are linked to the fixed support 62 via translation stages 71, 73, 75, 77, and four pairs are linked to the balance wheel 81 via translation stages 72, 74, 76, 78. The central part 59 is movable, has a cylindrical shape, preferably a circular shape, and forms an intermediate member movable between the support 62 and the movable element 80. The movable element 80 comprises a preferably annular balance wheel 81 provided with four extensions 82 extending towards the inside of the ring. The extensions 82 extend so that they are substantially orthogonal to the tangent of the ring, so that the secondary blades 72, 74, 76, 78 and the main blades 63, 65, 67, 69 of the translation stages are substantially perpendicular.

[0056] exist Figure 8In the figure, the flexible guide 60 of the fourth embodiment is cut into two parts. On the left, the first part includes the support 62 and the four pairs 71-61, 73-64, 75-66, 77-68. On the right, the second part includes the four pairs 72-63, 74-65, 76-67, 78-69 and the balance wheel 81. The central part 59 is shown in Figure 8 In the assembled position, the two parts are superposed, wherein the middle part 59 merges into one. Therefore, the two parts extend in two parallel planes.

[0057] Fig. 9 A fifth embodiment of the flexible guide 70 in FIG. 7 comprises a translation stage 86, 87, 88 arranged in the center of the flexible guide 70. The flexible guide 70 comprises three pairs, each pair consisting of a main flexible blade 83, 84, 85 and a translation stage 86, 87, 88. The pairs are distributed angularly around a virtual center 89. The main flexible blades 83, 84, 85 are each connected to the translation stage 86, 87, 88 at a first end and to a movable element 90 at a second end. The movable element 90 is annular. Each translation stage 86, 87, 88 is connected to a fixed support 92 via a secondary flexible blade and is connected to the main flexible blades 83, 84, 85 via a rigid part.

[0058] In the embodiments described above, the translation stage is configured so that when the flexible guide is stationary, the one or more secondary blades are substantially perpendicular to the primary flexible blade. However, other alternative embodiments are possible, such as Figures 10 to 12 The embodiments shown in , they can advantageously replace the translation stages described in the above embodiments.

[0059] exist Fig.10 , a first alternative translation stage 95 allows the primary flexible blade 96 to guide the secondary flexible blade 97 at an angle α different from 90°. The primary flexible blade 96 is assembled with a rigid part 98, forming the angle α. The rigid part 98 takes the shape of a bend with two perpendicular sections. The secondary flexible blade 97 connects the first section of the bend to the support 99, while the second section of the bend is joined by the primary flexible blade 96 at an angle α. The angle α is preferably comprised between 20° and 80°, or even between 30° and 60°.

[0060] Fig.11A dual translation stage 100 is shown, comprising a first curved rigid portion 104 connected to a primary flexible blade 101, a secondary flexible blade 106 connected to a second straight rigid portion 103. The second rigid portion is connected to a support 102 via two third flexible blades 107. In the static position, the secondary flexible blade 106 and the third flexible blade 107 are substantially parallel and substantially perpendicular to the primary flexible blade 101 due to the first curved rigid portion 104. The secondary blade 106 and the third blade 107 are attached to the same face of the second rigid portion 103, the secondary blade 106 being arranged between the two third blades 107.

[0061] Fig.12 The alternative translation stage 105 shown in comprises a straight rigid part 109. Two secondary flexible blades 112 are arranged on either side of the rigid part 109 (from the long side of the rigid part 109 to connect it to the secondary flexible blades 112. The primary flexible blades 108 are connected to the short sides of the rigid part 109.

[0062] In the figures showing different embodiments of the flexible guide, the flexible blade is a flat blade. However, the flexible blade may also include a thicker or thinner portion, or may include a neck, such as Fig.13 Thus, the top blade 110 includes a thicker portion 113 in the middle (which is stiffer) and thinner portions 114 at the ends. The bottom blade 115 is thick throughout its entire length but includes two necks 116 that are thinned at the ends to allow the blade 115 to flex.

[0063] Fig.14 A flexible assembly 120 is shown which can replace one or more flexible blades of the flexible guide described above. Assembly 120 includes two staggered blade pivots and a central rigid portion 117. Each of the staggered blade pivots includes a pair of staggered blades 121, 122 connected to the rigid portion 117. The rigid portion 117 is straight, with each pair of two pairs of staggered blades 121, 122 arranged at one end of the rigid portion 117. Blades 121, 122 are attached to elements 118, 119 disposed on either side of the rigid portion 117. These elements 118, 119 can be fixed supports, movable elements or intermediate elements of the flexible guide as described above. Blades 121, 122 in a pair are close together at the rigid portion 117 and are far apart at the elements 118, 119.

[0064] The invention further relates to a resonator mechanism, in particular for a timepiece movement (not shown in the figures).The resonator mechanism is provided with a flexible guide according to one of the embodiments described above.

[0065] It goes without saying that the invention is not limited to the embodiments described with reference to the drawings and that alternatives may be considered without departing from the scope of the invention.

[0066] In particular, a greater or lesser number of pairs of main flexible blades and translation stages than the described example may be considered.

[0067] In an alternative embodiment, one or more translation stages do not include a rigid portion. Thus, one or more secondary flexible blades are attached to the primary flexible blade at one end and to a fixed support, a movable element or a central portion at the other end. The secondary flexible blades and the primary flexible blades may be attached to each other directly or by a thin flexible portion.
