Description

  The present invention relates to a device for pivoting an arbor of a watch movement, said device being indirectly connected to the ground plate of the movement by means of a jewel fitted in the setting and through which the arbor of the arbor passes.

  The invention relates to the field of watch arbor for watches, and more particularly to the guidance of true pivoting.

  Mechanical watches have a relatively isochronous progression. However, the expression “relatively” leaves room for the progress to fluctuate within a range from zero seconds to several tens of seconds per day.

  One cause of such variation in progress is the difference in the tempo behavior of the balance of the balance between the two horizontal positions. Such a difference in behavior is caused, for example, by the difference in the balance spring power that is closer to the tenon in one horizontal position than in the other horizontal position combined with the play of the tenon in the jewel.

  In fact, if the stone is parallel to the gemstone in a conventional assembly, the horn behavior is not stable in the horizontal position. This is due to the pivoting of the hozo on the horizontal stone and the play in the jewel.

  The basic function of the stone is to reduce friction on the horn and to provide good oil dispersion.

  The present invention proposes to describe various means for influencing the behavior of the tenon and thereby influencing the progress of the watch. By these means, the behavior can be influenced, i.e. the behavior can be adjusted, in particular the progress in two horizontal positions can be equalized.

  First, means for influencing the behavior of the balance of the balance at the plurality of horizontal positions are illustrated in FIGS. 3-11 in a non-limiting manner. Next, means for achieving consistency of progress at different locations by modifying the effect on the tenon are illustrated in FIGS. Of course, some of these figures can be combined, and methods for implementing such combinations will be known to those skilled in the art.

  The present invention relates to a device 10 for pivoting an arbor 1 of a timepiece movement 100, said device 10 comprising a jewel 3 fixed in a setting 7. This jewel 3 is passed by a arbor 1 of an arbor 1 having a rotation axis D. While this description applies to the preferred case of guiding a true pivot, the present invention can of course be used advantageously to guide other arbors such as ankle hozos. Here, the arbor 1 is the true of a spring-equipped balance.

  The receiving stone 4 is indirectly fixed to the main plate 6 of the movement 100 by at least the setting 7. In the illustrated embodiment, the setting 7 is supported by a cabochon 9, which is fixed to the main plate 6.

  In accordance with the present invention, the stone 4 includes a first and only bearing surface 5 arranged to abut and cooperate with the distal end of the hozo 2. On the other hand, the cylindrical portion of the hozo 2 cooperates with a generally olive-like orifice 31 provided in the jewel 3.

  In an economical embodiment, the bearing surface 5 is flat, as can be seen in particular in FIGS. 1, 3, 4, 5, 7, 8, 9, 13, 15, 16.

  The device 10 according to the invention has a cant angle where the perpendicular N to the common tangential plane PT with respect to the hoso 2 and the first bearing surface 5 is not zero with respect to the axis D at the position where the hoso 2 abuts against the stone 4. It is arranged so as to be inclined at θ.

  Such an arrangement avoids the disadvantages of the prior art that the hozo oscillates and slides on a horizontal cradle within the range allowed by the play of the hozo within the jewel orifice. Actually, by tilting the receiving stone 4, it is possible to influence the position of the tenon at the plurality of horizontal positions. An inclination of about 3 ° does not interfere with the lubrication and can hold the required oil droplets on the side. Although the efficiency is slightly reduced due to the slight increase in friction at the flat position caused by the tilting position of the stone, the friction value at the suspended position is close to the friction value at the flat position, which is the desired goal. is there. In short, it is not a problem of minimizing friction, but a problem of equalizing friction at a plurality of different spatial positions.

  Both the perpendicular N and the axis D define a so-called pedestal plane PCP, which has a first angular orientation with a yaw angle α with respect to the reference direction DR of the ground plane 6.

  In accordance with the present invention, the device 10 can be adjusted within the gem orifice 31 to adjust and adjust the advancement of the movement 100 in which the device 10 is incorporated by reducing the difference in advancement between the two horizontal positions. Adjusting means 20 for influencing the movement of the hozo 2 is included. More specifically, these adjusting means 20 are means for adjusting the yaw angle α and / or the cant angle θ. These adjustment means should not be confused with the elastic arms or springs of certain prior art bearings. The elastic arm or spring of the specific prior art bearing is generally intended only for the holding function and / or the elastic restoring function, and in any case, a reproducible adjusting means cannot be formed.

  Due to the inclination of the cant angle θ of the sole bearing surface 5 on the stone 4 as seen in particular in FIG. 1 with respect to the axis DO of the hozo 2, the movement of the hozo 2 in the jewel orifice 31 and this movement The resulting time measurement method can be influenced.

  Due to the inclination of the yaw angle α of the pedestal plane PCP with respect to the reference direction DR corresponding to the ground plane 6 that receives the device 10 as seen in FIG. 2, the time measurement method, in particular the progress between two horizontal positions, Can be corrected and adjusted.

  Preferably, the jewel 3 and the jewel 4 are both fixed in the setting 7, and the jewel 4 is pressed into the setting 7 toward the jewel 3 by at least one shock absorbing spring 8, and the shoulder of the setting 7. Abuts against the part.

  In a particular version of the invention, in some of the variants, these adjusting means 20 are for or surround the setting 7 installed to pivot relative to the main plate 6; And positioning means 21 for the cabochon 9 movably installed with respect to the main plate 6.

  The mobility of the setting 7 with respect to the main plate 6 may be indirect. This is the case in FIGS. 12 and 15 in which the setting 7 pivots with respect to the cabochon 9 and the cabochon 9 is immobilized with respect to the main plate 6.

  The mobility of the cabochon 9 with respect to the main plate 6 is preferably pivotal with no play or preferably with friction as seen in FIGS. 13 and 14, or the periphery of the main plate 6 as seen in FIG. Limited to differential translational movement with respect to the ground plane 6 with reduced play that only allows twisting of the stone 4 relative to the ground plane 6 at three points on the part.

  Of course, the mobility of the setting 7 relative to the cabochon 9 and the mobility of the cabochon 9 relative to the ground plane 6 can be combined, but this results in a loss of simplicity of adjustment and progress between different positions. In most cases, it is sufficient to adjust only the setting 7 or the cabochon 9.

  Advantageously, the adjusting means 20 includes angle index means 22 for maintaining the adjustments made to the watch. These angle index means 22 also surround the setting 7 as seen in FIG. 12 and / or the setting 7 arranged to pivot with respect to the ground plane 6 and / or as seen in FIG. 6 in the case of the cabochon 9 movably installed with respect to the case 6, in which the setting can take a plurality of separate positions in the former case, and in the latter case the teeth integrated with the cabochon 9 by the toothed pinion 25 The fine crown 94 can be finely adjusted.

  FIG. 12 shows a variation with a slanted cradle 4 and a setting 7 that can be indexed to a plurality of distinct positions to implement and maintain the advancement adjustment. The cabochon 9 includes a cell 93 that can store a finger 72 integral with the setting 7, which together form the adjusting means 20 and the index means 22. The stone 4 is driven in the setting 7 or indexed.

  As shown, the present invention can be implemented in various variations.

The setting 7 is installed in the cabochon 9 in a state inclined with respect to the second reference surface 91 at a single predetermined position. In FIG. 8, the cabochon 9 is installed in alignment with the balance axis D, and the setting 7 is installed coaxially with the cabochon 9. The setting 7 includes two housings 75, 76 parallel to each other, which are inclined by a value of the cant angle θ, which is preferably about 3 °. The first housing 75 is for a jewel for guiding the hozo 2, so that the passage orifice 31 is inclined with respect to the axis D of the hozo 2. The other housing 76 is for receiving the receiving stone 4. The receiving stone 4 is substantially parallel to the jewel 3 and is held in the cabochon 9 by the shock absorbing spring 8. In this way, the end of the horn 2 abuts on the flat bearing surface 5 of the cradle 4 at a cant angle θ that is the same as the inclination angle θ of the cradle and jewel in the setting 7.

  More specifically, the cabochon 9 includes a housing 92 for receiving a setting 7 that includes an outer surface 71 that is inclined relative to the axis D0 of the orifice 31 at a single predetermined position. ing. The housing 92 is parallel to the direction of the second reference surface 91 of the cabochon 9.

  In particular in the variant shown in FIGS. 9 to 13, the cabochon 9 includes a housing 92 for receiving the setting 7, which housing 92 is relative to the second reference surface 91 of the cabochon 9 in a single predetermined position. Is inclined. This setting 7 includes an outer surface 71, which is a rotating body, coaxial with the axis D 0 of the orifice 31 of the jewel 3.

  FIG. 9 therefore shows a cabochon 9 which is a substantially rotating body, installed in alignment with the axis D of the balance by means of a cylindrical shoulder 91 cooperating with the perforation 63 of the main plate 6. Comprises a housing 92 for receiving the setting 7, which is inclined by a value of a cant angle θ which is preferably about 3 °. This setting 7 comprises two housings parallel to each other, one housing 75 for the jewel 3 for guiding the hozo 2 so that the passage orifice 31 is on the axis D of the hozo 2 The other housing 76 is for receiving the receiving stone 4 substantially parallel to the gemstone 3 and is held in the cabochon 9 by the shock absorbing spring 8. Is done. Therefore, the end portion of the hozo 2 comes into contact with the flat bearing surface 5 of the receiving stone 4 at the same cant angle θ as the inclination angle θ of the setting 7 in the cabochon 9. In FIG. 13, the same assembly can be seen, but this FIG. 13 shows such an inclined setting 7 in the cabochon 9, which is assembled straight and installed in the ground plane 6 by friction, and It contacts the main plate 6. The cabochon 9 includes a screw hole 93 for adjusting the yaw angle α using a tool such as a screwdriver. The advancement can be adjusted by adjusting the yaw angle α, and the adjustment can be maintained under the action of friction. .

  In particular in the variant shown in FIG. 16, the first bearing surface 5 is perpendicular to the axis DO of the orifice 31 of the jewel 3 for guiding the hozo 2. The setting 7 is installed in the cabochon 9 parallel to the second reference surface 91. The second reference surface 91 is held in an inclined state with respect to the complementary second bearing surface 61 of the main plate 6. More specifically, the cabochon 9 is inserted with play in the housing 64 of the main plate 6, and the cabochon 9 is mounted on the periphery of the cabochon 9 to adjust both the cant angle θ and the yaw angle α. Are firmly held on the main plate 6 by three screws 23 each including a groove 27 for holding the flange 96. Preferably, as shown, at least one of the screws 23 abuts the surface 61 of the main plate 6 by a shoulder 241 of the collar 28 that delimits this groove 27 to facilitate adjustment. Retained.

  In the modification of the present invention shown in FIG. 3, the perpendicular of the first bearing surface is inclined at a cant angle θ of about 3 ° with respect to the axis DO of the orifice 31 of the jewel 3 for guiding the hozo 2. doing. The setting 7 is installed in the cabochon 9 parallel to the second reference surface 91.

  In particular in the variant shown in FIG. 14, the adjusting means 20 includes means 24 for driving the pivoting of the cabochon 9. In FIG. 14, the cabochon 9 supports an inclined support stone 4, which includes a peripheral tooth 94 that meshes with an actuating pinion 25 having a screw hole 26, which is frictionally installed in the main plate. Is used to adjust the yaw angle α by pivoting the entire cabochon 9, and this adjustment can be maintained under the action of friction.

  In particular, in the variant shown in FIG. 9, the complementary bearing surface 61 of the ground plane 6 is a perforation 63 substantially parallel to the axis D, and the first bearing surface 5 is relative to the axis DO of the orifice 31 of the gem 3. And vertical. The setting 7 is installed in an inclined housing 92 of the cabochon 9 so as to be inclined with respect to the cylindrical second reference surface 91 at a single predetermined position.

  In particular, in the variant shown in FIG. 7, the complementary bearing surface 61 of the main plate 6 is a perforation 63 inclined at an inclination of about 3 ° with respect to the axis D, and the first bearing surface 5 is the orifice 31 of the jewel 3. The jewel 3 is inclined with respect to the axis of the hozo due to the inclination of the cabochon in the main plate. The setting 7 is coaxially installed in the cabochon 9 so as to be parallel to the cylindrical second reference surface 91 at a single predetermined position. Therefore, the end portion of the horn 2 abuts on the flat bearing surface 5 of the receiving stone 4 at a cant angle θ which is the same as the inclination angle of the cabochon 9 in the main plate 6.

  In particular, in the modification shown in FIG. 15, the cabochon 9 and the setting 7 are straight and coaxial, and the cabochon 9 is installed to pivot within the main plate 6. The normal of the first bearing surface 5 is inclined with respect to the axis DO of the orifice 31 of the jewel 3. The setting 7 is installed in the cabochon 9 parallel to the second reference surface 91. The shock absorbing spring 8 cooperates with a rib 41 or a groove 42 on the surface of the receiving stone 4 opposite to the bearing surface 5 at the end of the hozo 2. The cabochon 9 includes a plurality of housings 95, 95A, 95B, 95C, 95D, for receiving and locking the loop 82 or the end arm 83 of the shock absorbing spring 8 so that the lyre of the spring 8 The setting 7 can be indexed in various positions via the member, and the spring 8 is indexed in the notch of the cabochon 9 in the housing 95.

  In some variations, the pedestal 4 includes a concave, advantageously off-centered, in particular spherical or conical surface for receiving the distal portion of the hozo 2, which center is The offset concave surface includes an inclined edge, particularly on the balance spring side, whereby the true 1 can be removed from the vertical position, which affects the behavior of the hozo 2 in the horizontal position. Accordingly, the bearing surface 5 is a recess 51 that is offset from the axis DO of the orifice 31 of the jewel 3 as seen in FIG. 6, or a V that is centered on the axis DO as seen in FIG. The first groove 52 having a letter-shaped outer shape, or the second groove 53 having a V-shaped outer shape shifted in the center with respect to the axis DO as shown in FIG. 10, but is not limited thereto. It is not something.

  In a particular embodiment, the device 10 includes means 30 for pulling or pushing back the hozo 2 in a direction substantially perpendicular to the axis D of the hozo 2. By implementing means 30 for pulling or pushing back the hozo 2 in a direction substantially perpendicular to the axis D of the hozo 2, the position of the hozo in the horizontal position is affected.

  In the first variant seen in FIG. 4, these traction or pushback means 30 are formed by electrets or magnets 30A that generate an electrostatic or magnetic field, and the hozo 2 made of a conductive metallic material is sensitive to these fields. And receives a force to press the hozo 2 against at least one edge of the orifice 31 of the jewel 3. When the cradle 4 is tilted, the advancement adjustment is further improved by the field tilt in the same plane as the normal to the bearing surface 5.

The inclination of the entire setting 7 can affect the position of the hoso 2 in the horizontal position. Further, by modifying the influence on the hozo 2 by acting on the cabochon 9 or by combining the action on the cabochon 9 and the action on the setting 7, the progress can be made equal between a plurality of different positions. .

  By using the inclined receiving stone 4 and the receiving stone 4 having a concave housing and rotating the receiving stone 4 above or below the balance, the progress in the corresponding horizontal position is affected.

  This principle is based on the rotation of the receiving stone in the shock absorber formed by incorporating the shock absorbing spring 8 in the cabochon 9, the rotation of the setting 7 and the receiving stone 4, the rotation of the entire shock absorber, and the balance of the balance. Applicable to rotation.

  All the solutions described above are applicable to shock absorbers with conventional settings, or shock absorbers with suspended or semi-suspended settings.
