Definitions

  • the present invention relates to a mechanical timepiece equipped with a device for adjusting the swing of a rotating mobile, in particular the swing of a balance.
  • Another known variant consists in having a fixed screw, which can serve as a reference because once screwed the watchmaker will no longer touch it, and an adjustment screw, which depending on the direction of screwing will raise the balance bridge or lower it to the manner of a screw-nut or screw-nut system.
  • the watchmaker who adjusts the balance of the balance must act on the adjustment screw (s) by turning it (s) successively and repeatedly until the board reaches a height defining a correct balance for the balance.
  • said bridge comprises at least one support configured to be in contact with said plate; said at least one lever arm being disposed between said at least one support and said at least one foot.
  • said at least one board being configured to be deformed so that the distance between said at least one board and said plate varies when said force is applied to said at least one lever arm.
  • the deformation of said at least one board makes it possible to vary the distance between said at least one board and said plate varies when said force is applied to said at least one lever arm.
  • said at least one lever arm being configured to be deformed when said force is applied to said at least one lever arm.
  • the deformation of said at least one lever arm makes it possible to vary the distance between said at least one board and said plate varies when said force is applied to said at least one lever arm.
  • said mechanical link is a point link, a rectilinear linear link and / or a pivot link.
  • said at least one lever arm comprises at least one fixing opening configured to receive at least one fixing member so as to fix said bridge to said plate.
  • said at least one board comprises said receiving opening.
  • said receiving opening comprises a first center and / or said at least one fixing opening comprises a second center.
  • said at least one foot is between said first center and said second center.
  • said mechanical link is aligned between or with said first center and said second center, preferably said mechanical link is aligned on an axis formed by said first center and said second center.
  • said rectilinear linear link and / or said pivot link form or form an angle of between 70 ° and 90 °, in particular between 80 ° and 90 ° and preferably between 85 ° and 90 ° with respect to said axis formed by said first center and said second center.
  • said at least one foot is closer to said at least one lever arm than to said at least one board.
  • the present invention shown in figures 1A and 3A on a plate, makes it possible to adjust the balance wheel easily, automatically thanks to a bridge 100 for balance 210 and this even if a bridge 100 for balance 210 is nested.
  • Said bridge 100 for balance 210 or balance 210 comprises a receiving opening 111 , comprising a first center 115 , to receive one end of the axis of said balance 210 at its said first center 115 or at the very least close to its said first center 115.
  • the other end of the axis of said balance 210 rests in a housing provided for this purpose on a plate 200.
  • said balance 210 is located between said bridge 100 according to the invention and said plate 200 , on which said bridge 100 is fixed and positioned by means of at least one fixing member 205 which may be in the form screw 205.
  • Said at least one screw 205 is configured, or said at least one fixing member 205 is configured to apply a force, more precisely a tension and / or a torque, to said bridge 100.
  • Said bridge 100 comprises at least one board 110 , at least one lever arm 120 , at least one foot 130 and / or at least one support 140 according to the embodiments.
  • said bridge 100 is transverse and may include a board 110 , two lever arms 120 , and two feet 130 .
  • said bridge 100 is suspended and may include a board 110 , a lever arm 120 , a foot 130 and a support 140.
  • Said at least one board 110 is configured to be moved or, according to one embodiment, to be deformed so that the distance between said at least one board 110 and said plate 200 varies, more exactly, said at least one board 110 comprises a first surface 119 , and it is this distance between the first surface 119 of said bridge 100 and said plate 200 which varies. As follows from the preceding paragraphs, it is said at least one board 110 which comprises said receiving opening 111 , as shown in particular by the figures 1A , 2 and 3C , and when the distance between the first surface 119 of said bridge 100 and said plate 200 is optimal, said bridge 100 is buckled.
  • this variation is possible thanks to said at least one lever arm 120 , which is configured to move said at least one board 110 when said force is applied to said at least one lever arm 120.
  • said at least one lever arm 120 is moved closer to said plate 200 , and, by pivot, by means of said at least one foot 130 , said at least one board 110 is moved or even deformed in an elastic manner.
  • said bridge according to the first embodiment is fixed at its two ends. Therefore, when at least one of the two lever arms 120 is brought closer to said plate 200 , said at least one plate 110 is moved or even deformed elastically because the other end is fixed via at least one fixing member 205 to said plate 200.
  • this variation is possible thanks to the deformation of said at least one lever arm 120.
  • said at least one support 140 being in contact with said plate 200 causes said at least one lever arm 120 to deform elastically and therefore moves said at least one board 110. It is certainly important to specify that by displacement or variation of the distance between the first surface 119 of said bridge 100 and said plate 200 , and this independently of the embodiment, is achieved by increasing or decreasing the angle between the first surface 119 of said bridge 100 and said plate 200.
  • said at least one screw 205 is introduced into at least one fixing opening 121 , comprising a second center 125 , included in said at least one lever arm 120 and fixes said bridge 100 to said plate 200.
  • said at least one lever arm 120 is distant from said plate 200 , more exactly, said at least one lever arm 120 comprises a second surface 129 which faces said plate 200.
  • Said at least one foot 130 mentioned upstream of the description, comprises, for its part, a contact surface 139 , that is to say a surface which could be considered as being more or less the base 139 of said bridge 100.
  • said at least one foot 130 is configured or said contact surface 139 is configured to be in contact with said plate 200 so as to make a mechanical connection, which can take the form of a point, linear rectilinear and / or pivot connection. , and to transmit said force applied to said at least one lever arm 120 so as to move said at least one board 110 .
  • said at least one foot 130 is between said first center 115 and said second center 125 , preferably said at least one foot 130 is closer to said at least one lever arm 120 than to said at least one board 110 , and on the other hand, the distance between said contact surface 139 , that is to say say the base 139 of said bridge 100 and said first surface 119 , the first surface 119 of said bridge 100 , is shorter than the distance between said contact surface 139 and said second surface 129. This can also be the case in the second mode. of achievement.
  • said at least one lever arm 120 can produce a lever by means of said at least one foot 130 , and said said mechanical link is aligned between or with said first center 115 and said second center 125 , preferably said mechanical link. is aligned on an axis formed by said first center 115 and said second center 125.
  • said mechanical link that is to say said rectilinear linear link and / or pivot, forms or forms an angle between 70 ° and 90 °, in particular between 80 ° and 90 ° and preferably between 85 ° and 90 ° relative to said axis formed by said first center 115 and said second center 125 so as to adjust the swing of the balance by determining the inclination of said at least one board 110 through the inclination of said first center 115 and said second center 125.
  • the inclination of said at least one board 110 is determined by the elevation of said first center 115 by report t at said second center 125.
  • the first embodiment could be provided with said at least one support 140 and the second embodiment could be deprived of said at least one support 140 on condition of having at least one holding member configured to maintain the distance between said support. plate 200 and said second surface 129 and to deform elastically in the manner of an elastomer.
