Definitions

  • the present invention relates to a timepiece control device comprising an inertial balance comprising a balance shaft arranged to be pivotally mounted in the timepiece, a balance bridge supporting a bearing arranged to hold one end of the axis of rotation. balance wheel, a hairspring having an inner end secured to the rocker and an outer end secured to a pin, and finally a piton fixing mechanism comprising a housing carried by the rocker arm and arranged to receive the pin while allowing to adjust longitudinally the position of the latter, the fixing mechanism further comprising an elastic arm arranged to press laterally on the stud so as to immobilize the stud against a wall of the housing.
  • Regulating members comprising a balance and a hairspring whose inner end is fixed rigidly to a hoop driven on the axis of the balance, and whose outer end is fixed rigidly to a pin carried by an angularly displaceable peg holder concentrically to the axis of the balance.
  • the bolt carrier is pivoted to hard friction on a part of the cock (or balance beam) concentric with the balance shaft.
  • a watchmaker can adjust the angular position of the stud and the outer end of the hairspring by simply pivoting the bolt carrier relative to the pendulum. This manipulation is important because the angular position of the outer end of the spiral must be such that the plateau pin is in the anchor-balance axis when the balance is in its equilibrium position.
  • the adjustment of the position of the spiral spring relative to the balance shaft must be precise. In fact, an off-centering of the spiral spring or a defect of perpendicularity with respect to the balance shaft generates significant chronometric defects, in particular at the level of the isochronism of the regulator.
  • the pin must be perpendicular to the plane of the spiral spring and positioned accurately to ensure a concentric development of the spiral spring. In practice, the adjustment of the position of the peak is delicate because access is restricted and the parts concerned are very small. With traditional metal alloy spiral springs, once the outer end of the balance spring is fixed to the balance bridge by the pin and the bolt carrier, the residual deviations from the ideal three-dimensional shape of the spiral spring can still be corrected by deformation. Plastic end of the spiral spring.
  • the spiral spring is made of a brittle material, such as silicon, diamond or quartz
  • adjustment by plastic deformation as above is not possible.
  • the use of a pin imposes very tight manufacturing tolerances as well a robust piton-spiral assembly, so as to obtain the most perfect perpendicularity possible between the axis of the peak and the plane of the spiral spring. It is easy to understand that this imperative represents a major difficulty on an industrial scale, when we know that the simple fact of immobilizing the stud in its housing by tightening a screw can suffice to distort its orientation. In addition, it is common to drop and misplace the clamping screw during the adjustment operation.
  • an object of the present invention is to provide a pin attachment mechanism, which offers the possibility of adjusting the position of the stud relative to the balance beam and then immobilize the piton more easily. use a screw.
  • the Swiss patent document CH 76,336 describes a sprung balance regulator device which comprises a piton fixing mechanism and which corresponds to the definition given in the introduction.
  • the balance bridge carries a cockpit which has an ear provided with a lateral notch serving as housing for the peak. Once the stud inserted in the housing, it is held in place by a spring attached to the balance bridge. The spring acts by pressing the pin against the bottom of the notch so as to immobilize it.
  • a screw eccentric head is still provided to move the spring of the piton so as to release it.
  • This prior solution has certain defects.
  • the cockpit is rigidly mounted on the balance bridge, the orientation of his ear can not be changed.
  • the position of the housing provided to receive the peak is fixed once and for all.
  • another object of the present invention is therefore to provide a sprung balance regulator device that also allows to adjust the position of the housing in which the pin is immobilized.
  • the present invention achieves this goal by providing a timepiece controller in accordance with the appended claim 1.
  • a watchmaker can easily attach the bolt to the bolt carrier without using a screw, and in addition, he can adjust the angular position of the bolt and the outer end of the hairspring simply by pivot the bolt carrier relative to the balance, as simply as if the bolt was fixed by a screw.
  • the resilient arm can be rotated relative to the balance bridge as well as relative to the bolt carrier. It is therefore particularly possible to rotate the elastic arm and the bolt carrier together.
  • the indications “above” and “below” refer to the sectional view of the figure 2 .
  • the underside being the side of the hairspring.
  • the indication “outward facing” is to be understood as meaning turned in the opposite direction to the axis of the balance.
  • the figures show a balance-sprung regulator member for a timepiece corresponding to a particular embodiment of the invention.
  • the balance 7 whose axis is rotated between two bearings.
  • one of these bearings (referenced 11) is supported by the rocker bridge (or cock) 9 via a cockpit 13, while the other bearing is mounted in the plate (not shown ).
  • the balance is associated with a hairspring 1 whose central end is fixed to the axis of the balance.
  • the cock 9 also serves to support an assembly consisting of a stud 3, a stud holder 5 and an elastic arm 15.
  • This assembly is intended to position the outer end 1a of the spiral 1.
  • the end 1a is first fixed rigidly to the stud by gluing. To do this, we first introduce the end of the spiral in a piton notch (not referenced but visible on the figure 2 ). The hairspring is then locked in the notch by gluing.
  • the invention is not limited to a particular method of fixing the end 1a of the spiral on the peak.
  • the end 1 a could, just as well, for example be attached to a conventional bolt pin. Or, according to yet another variant, it is possible to provide the stud 3 and the spiral 1 of material in one piece.
  • the bolt carrier 5 essentially consists of an annular portion concentric with the balance shaft, and an arm-shaped extension (hereinafter called "ear") which carries the bolt 3 and which extends radially relative to the axis of the balance 7, towards the outer turns of the spiral.
  • the ear of pin holder 5 has a housing 17 oriented parallel to the axis of the balance 7 and in which the pin and inserted longitudinally.
  • the bolt carrier 5 is pivoted to hard friction by its annular portion on the brace 13 which is concentric with the pendulum. With this characteristic, a watchmaker can change the position of the stud 3 simply by pivoting the stud holder 5 relative to the cock and the pendulum.
  • the bolt carrier is preferably made of silicon, but that it could also be made of another material.
  • the bolt carrier could be made of metal or composite material. If the peak is made of metal, it is preferably formed by galvanic deposition according to the LIGA technique.
  • the housing 17 is formed by a through-hole formed in the ear of the bolt carrier 5. It can be seen that, in the illustrated example, the through-hole has a cross-section in the form of an isosceles triangle; one of the vertices of the triangle being directed towards the axis of the balance. Referring now to the figure 2 it can be seen that the housing 17 is oriented parallel to the axis of the balance.
  • the peg holder 5 has a flange 19 which protrudes under the underside of the ear.
  • the rim 19 has the shape of a groove which is disposed in the extension of the inner wall of the housing 17.
  • the rim 19 thus extends the housing 17 in the form of a groove whose bottom is turned towards the axis of the balance.
  • the total length of the housing 17, with its extension is greater than the thickness of the ear of the peg carrier.
  • the shape of the cross section of the housing at its extension is not that of a triangle, but that of a V.
  • the opening of the groove is oriented towards the outside of the balance.
  • the pin is arranged to bear simultaneously against two faces of the inner wall of the housing 17 of triangular shape. These two faces of the inner wall extend parallel to the axis of the balance and together define a groove whose bottom is oriented towards the axis of the balance. In the illustrated example, the two faces in contact with the pin 3 merge between them at an angle of 60 degrees. It will be understood, however, that the invention is not limited to this particular value of the angle between the faces of the triangle.
  • the shape of the stud 3 is essentially cylindrical.
  • One advantage of the rotational symmetry inherent in the cylindrical shape is that the position of the stud relative to the stud holder 5 can be adjusted, not only longitudinally, but also in rotation.
  • This additional possibility may be advantageous when the spiral spring is made of a brittle material. Indeed, when the spring is made with such a material, it is in principle not possible to correct a possible deflection of the spring plastically deforming its end.
  • the figures 1 and 2 still show an elastic arm 15 arranged to press laterally on the stud 3 so as to immobilize it against the wall of the housing 17.
  • the elastic arm 15 is pivoted on the surface lower of the peg carrier 5 via an annular portion 15a which comes from the material with the elastic arm 15 and which is shown in broken lines on the figure 1 .
  • the elastic arm 15 could also be pivoted directly on the cock 9 or the cockpit 13.
  • the elastic arm 15 is shown in a first angular position where it immobilizes the bolt 3 by pressing laterally directly on the stud at the rim 19, where the housing 17 is extended in the form of an open groove.
  • the elastic arm 15 is bent so that its shape generally reminds that of a hook.
  • the end of the elastic arm has a spring-jumping profile with two substantially straight segments which define at their junction a vertex 15b.
  • the top 15b is located near the tip-shaped end 15c of the elastic arm.
  • the distance separating the tip 15c from the axis of the balance is normally greater than the distance separating the axis of the peak 3 from this same balance shaft.
  • the distance separating the vertex 15b from the axis of the balance is preferably less than the distance between the axis of the peak and the axis of the balance.
  • the arm 15 is shown in a first position where it passes under the ear of the stud holder 5 so as to bypass the stud 3 so that a distal portion of the arm comprising the end 15c as well as the Summit 15b is on the other side of the peak. It will be understood that when the elastic arm is in this first position, it presses the outer side of the pin 3 so that the latter is biased towards the axis of the balance. In addition, it will also be understood that the reaction force of the stud on the elastic arm has a tangential component which has the effect of keeping the elastic arm in the position shown in FIG. figure 1 .
  • the resilient arm 15 is provided to be pivotable relative to the stud holder 5. If a watchmaker forces the elastic arm to pivot relative to the stud holder counterclockwise, the end of the arm slides on the piton 3 while being pushed towards the outside. At the moment when the vertex 15b crosses the bolt by sliding, the tangential component of the reaction force exerted by the bolt on the elastic arm changes direction and rapidly rotates the elastic arm 15 until it is completely disengaged from the pin 3. It is therefore possible to release the pin very easily by simply passing the elastic arm 15 of the first angular position illustrated on the figure 1 at a second angular position disengaged from the peak, by a simple rotation of the resilient arm counterclockwise.
  • the figures 3 and 4 show two variants of the embodiment which is the subject of the detailed description.
  • the variant represented in the figure 3A is virtually identical to that shown in figures 1 and 2 .
  • the elements represented in the figure 3A which are identical to those of figures 1 and 2 are designated by the same reference numbers. Comparing the figures 1 and 3A , it can be observed that, contrary to the piton 3 which was cylindrical, the peak 103 visible in the figure 3A has a flat surface.
  • the advantage of using a stud with a flat is to allow angularly wedge the piton against one of the inner walls of the housing 17.
  • the figure 3B is partial view similar to the figure 3A but showing an elastic arm 115 corresponding to a second variant.
  • the inner side of the elastic arm 115 still has in the vicinity of the top 115b a V-shaped seat formed at the junction two substantially straight segments.
  • the V-shaped seat makes it possible to better wedge the piton 115.
  • the housing arranged in the bolt carrier does not need to be triangular. It can have any form. In particular it can be constituted by an open groove along its entire length.
