Definitions

  • the present invention relates to a holding or supporting assembly of a spiral clockwork spring, comprising a pin and a stud holder.
  • a regulating member comprising a sprung balance device.
  • the inner end of the hairspring is fixed to a ferrule provided on the axis of pivoting of the balance.
  • a peg holder housing a pin in combination with a clamping screw for tightening the bolt against the portion of the hairspring engaged in the bolt carrier.
  • the bolt carrier is conventionally attached to a cock also serving to fix one end of the axis of the balance.
  • the rooster is designed to integrate a kitten equipped with a shockproof device for the balance shaft.
  • a known stud holder uses two rings. These two rings are rotatably mounted at the level of the kitten. Each ring includes a tuning fork or Y-shaped extension, this y-fork thus forming a housing.
  • a first ring is then used so that the stud is housed and fixed via a screw while the second ring is used for a setting element is housed.
  • This adjustment element makes it possible to adjust the limitation of the hairspring to adjust the step and therefore the frequency of the hairspring.
  • the object of the invention is to overcome the drawbacks of the prior art by proposing to provide a support or support assembly for a spiral watch spring which allows a simplified mounting or dismounting of the stud and a good maintenance of this one.
  • the present invention relates to a holding or supporting assembly of a clockwork spiral spring, comprising a stud and a cock on which is fixed a stud holder, characterized in that said stud holder comprises a holding means provided with a housing for housing the stud and a clamping means, at least said clamping means being movable relative to the holding means to block the stud in its housing.
  • the advantage of the invention is to allow, during the SAV, to disassemble the assembly "balance bridge-spiral silicon" easily. By unlocking the bolt through the clamping means, it is possible to simply remove the "balance spring - hairspring - bolt” portion of the "swing bridge - peg holder - damper” without risk of breaking the hairspring.
  • the holding means and the clamping means are in the form of an annular piece arranged to be rotatably mounted on a protrusion 8.
  • the holding means are in the form of a retaining ring 50 comprising receiving means of the stud 51 having two protuberances 52 projecting from said retaining ring 50 and being spaced apart from each other for forming a housing 53 in which the pin 7 can be housed.

  • the holding means are in the form of a retaining ring 500 comprising an elastic arm 512 extending from said ring and forming, with it, a housing 514 to accommodate the peak.
  • the clamping means are in the form of a clamping ring 600 comprising an armature 604 on which a pad 602 is arranged, the armature and the pad being arranged so that the rotation of the clamping ring relative to the retaining ring causes the appearance of a constraint exerted by said stud on said elastic arm to lock the mounting of the stud.
  • the clamping means are in the form of a clamping ring 600 comprising an armature 604 on which a structure provided with a groove is arranged, the groove being arranged so that the elastic arm can be inserted so that the rotation of said locking ring with respect to the retaining ring causes a deformation of said arm to lock the mounting of the stud.
  • the armature comprises at least two arms extending radially, interconnected by a cross member, the at least two arms being spaced apart so as to allow the bolt to be placed and locked without risk of contact with said arms.
  • the clamping ring and the retaining ring each comprise a positioning extension (56, 66) extending radially and allowing its gripping by a tweezers-type tool for rotating the clamping ring. and the retaining ring.
  • the positioning extension of the clamping ring and one of the arms of the armature form a single piece.
  • the positioning extensions (56, 66) of the clamping ring and the retaining ring are arranged to face each other when the bolt is locked so as to allow their simultaneous gripping to perform an angular adjustment of the position of the peak relative to the rooster.
  • the present invention proceeds from the general idea of providing a support or support assembly of a spiral clock spring for mounting / dismounting of the simplest piton.
  • FIG. 1 On the figure 1 is represented the holding or support assembly 1 according to the present invention.
  • a set 1 is mounted on a cock 2 and includes a bolt carrier 4 used to hold a bolt 7.

  • a groove extending on the periphery of the pad 83 or the catty 80 can be realized. to prevent a vertical displacement of the retaining ring 50.
  • This retaining ring 50 further comprises means for receiving the pin 51. These receiving means 51 comprise two projections 55 projecting, extending parallel outwards from the retaining ring 50.
  • These two protuberances 52 are spaced apart to form a housing space 53 in which the peg 7 can be housed. It is understood that the two protrusions protrude from the retaining ring 50 but also the rooster.
  • the clamping means 6 are in the form of a clamping ring 60.
  • This clamping ring 60 is closed or not and is dimensioned to be arranged at the pivoting device 8, as shown in FIG. holding ring.
  • This clamping ring 60 is thus forcibly engaged at the level of the pivoting device 8.
  • a groove extending on the periphery of the pad 83 or the cattery 80, parallel to that of the holding ring 50, may be made to avoid a vertical movement of the clamping ring.
  • the clamping ring is then located above the retaining ring.
  • This clamping ring 60 further comprises an elastic arm 62.
  • This arm 62 extends from said clamping ring 60 and has a free end 63.
  • This arm 62 extends from the clamping ring 60 in a direction substantially similar to that of the curvature of said clamping ring so as to form a space 64 between the clamping ring 60 and said arm 62.
  • the stud 7 is placed in the housing 53 of the retaining ring 50.
  • the clamping ring 60 is then rotated so that the end 63 of the elastic arm 62 is close to the peak.
  • the free end 63 of the elastic arm 62 is cleverly arranged to include a pin 65 to be partially in contact with the piton. Therefore, this forces the operator responsible for the assembly to force slightly during the rotation of the clamping ring 60.
  • the elastic arm 62 under the effect of this constraint, deforms so as to deviate. This causes a larger space for the insertion of the stud 7.
  • said elastic arm 62 tends to resume its rest or initial position.
  • the pin 7 has a body 71 arranged so that the hairspring can be attached and a head 72, said head having a conical profile 73 whose diameter is greater than that of the body 71.
  • the head of the pin 72 being able to bear on the two protuberances 52 projecting.
  • the resilient arm which comes into contact with the stud at the level of this conical profile then exerts a force perpendicular to the slope of the cone in order to press the Z stud against the two protuberances 52 protruding and XY in its housing.
  • the housing 53 and / or the peg 7 may include dishes to have an angular locking.
  • the retaining ring 50 and the clamping ring 60 each have a positioning extension 56, 66.
  • the clamping ring 60 and the retaining ring 50 therefore each comprise a radially extending extension, this extension allowing its gripping by a tweezers type tool.
  • these extensions 56, 66 are arranged so that they are facing each other when the pin 7 is locked as visible to the figure 3 . This arrangement makes it possible to rotate the clamping means 60 and the holding means 50 at the same time.
  • the holding ring 50 is made so that the receiving means of the stud 51 are in the form of a single extension 52 'pierced by an opening forming a housing 53' for the stud 7.
  • the ring clamping is arranged under the retaining ring and the peg 7 sees its head 72 have an inverted cone profile 73 '.
  • the assembly is similar so that the elastic arm 62 comes into contact with the cone 73 'of the peak 7 and generates a force perpendicular to the slope of the cone 73'. This force makes it possible to press studon 7 in Z in its housing 53 'and in XY in its housing.
  • the housing and / or the piton may include dishes to have an angular locking.
  • the holding means 5 are in the form of a retaining ring 500.
  • This holding ring 500 is closed or not and is dimensioned to be arranged at the pivoting device 8, the latter being of substantially circular shape .
  • This retaining ring is forcibly engaged at the pivoting device 8, that is to say at the level of the cattery 80 or the pad 83.
  • a groove extending on the periphery of the pad 83 or the catty 80 can be realized. to prevent a vertical displacement of the retaining ring 500.
  • This retaining ring 500 further comprises means for receiving the pin 510.
  • These receiving means 510 comprise an elastic arm 512 extending from said ring and forming, with it, housing 514 to accommodate the piton.
  • the clamping means 6 are in the form of a clamping ring 600.
  • This clamping ring 600 is closed or not and is dimensioned to be arranged at the pivoting device 8, as shown in FIG. holding ring.
  • This clamping ring 600 is therefore engaged by force at the pivoting device 8.
  • a groove extending on the periphery of the pad 83 or the catty 80, parallel to that of the retaining ring 500, may be made to avoid a vertical movement of the clamping ring 600.
  • the clamping ring 600 is then located above the retaining ring 500.
  • This clamping ring 600 comprises a stud 602 mounted on a frame 604.
  • the operating principle of this second embodiment uses this pad 602 to exert a stress on the elastic arm 512 in order to lock the pin 7.
  • the ring clamp 600 is rotated so that the pad 602 comes into contact with the elastic arm 512.
  • the stress exerted on the elastic arm 512 causes its deformation and thus the locking of the stud.
  • the armature 604 thus makes it possible to off-center the stud 602.
  • the armature 604 may be an arm 605 whose free end 605 'will be provided with said stud 602. This latter may be monoblock with the armature 604 or the free end 605 'will be provided with a hole so that the pad 602 is placed and fixed therein.
  • the armature comprises at least two arms 605a, 605b extending radially from the ring 600, these arms 605 being connected together by a beam or crossbeam 606.
  • This beam 606 is provided with a protuberance at level of which the stud is arranged. This configuration makes it possible to have a better rigidity than a reinforcement comprising a single arm.
  • the spacing of at least two arms 605 is sufficient to allow the piton 7 to lodge there without coming into contact with said arms during the rotation of the clamping ring.
  • one of the arms 605 of the armature 604 will be arranged so that, when the stud 7 is locked, said arm is opposite a positioning extension 516 of the holding ring 500.
  • This configuration then forms a possibility for the operator to pinch the arm 605 and the extension 516 via tweezers to angularly modify the position of the two rings 500 and 600. This thus provides a possibility of angular adjustment without modifying the locking of the bolt 7.
  • the armature 604 comprises four arms 605.
  • the spacing between the second arm 605 and the third arm 605 is chosen to accommodate the stud 7.
  • the fourth arm 605 is arranged to be used in cooperation with an extension 516 to change the angular position of the two rings 500, 600.
  • the pin 7 has a body 710 arranged so that the hairspring can be attached and a head 720, said head 720 having a cylindrical profile 730.
  • the body 710 further comprising a projection 740 forming a platform for the elastic arm 512 as visible to the figure 14 .
  • the armature 604 comprises an arm 609 whose free end 609 'ends with a structure 610.
  • This structure 610 is in the form of a part 611 having a groove 612 likened to a guide groove in which the arm elastic 512 of the retaining ring 500 is housed.
  • the tension of the elastic arm 512 allows the latter to be in permanent contact with one of the walls of the groove 612 of the structure 610. Therefore, during the rotation of the clamping ring 600 carrying the armature 604, the elastic arm 512 guided by the groove of the structure 610 then deforms. This deformation allows the elastic arm 512 to tighten the stud 7 and thus to lock the position of the latter.
  • the hairspring is of a diameter smaller than the size of the peg holder so that it is protected by said peg carrier.
  • this material has interesting non-magnetic properties.
  • silicon is a fragile material that breaks during excessive shocks.
