Definitions

  • the invention relates to a selector mechanism with clockwork columns, comprising a wheel set comprising a plurality of columns projecting above a base surface and separated by clearances, said columns and said clearances together forming slots extending along the along a profile, arranged to, in certain positions of said mobile, allow the introduction of a feeler or a pin into a said clearance in a transverse direction substantially normal to said profile and substantially parallel to said reference surface, and for in other positions of said mobile, stop a feeler or a pin on a transverse surface of a said column.
  • the invention also relates to a chronograph mechanism, comprising at least one such selector mechanism, controlled by a control means operable by the user.
  • the invention also relates to a timepiece, in particular a watch, comprising at least one clockwork movement, and at least one chronograph mechanism comprising at least one such selector mechanism, controlled by control means accessible to the user. .
  • the invention relates to the field of horological mechanisms with complications such as in particular chronograph mechanisms or striking mechanisms.
  • Timepiece mechanisms with complications such as chronograph mechanisms or striking mechanisms, commonly use function selection mechanisms comprising crenellated column wheels, blocking or authorizing the introduction of a feeler into a slot from the outside of the column wheel.
  • Some complex mechanisms implement column wheels at several levels, such as for example the striking mechanism described by the document EP2498146B1 in the name of MONTRES BREGUET, which includes mode selection means with a column wheel with several levels of superimposed ratchets.
  • These mechanisms effective for having several functionalities, are nevertheless very bulky, and their total thickness does not generally allow them to be housed in a watch of common dimensions.
  • the invention proposes to develop a selector mechanism of small thickness, capable of performing different functions, and in particular of developing a mobile with stop surfaces both on the outside and on the inside of the slots of a mobile column, including but not limited to a column wheel.
  • the invention relates to a selector mechanism 100 with clockwork columns, which comprises a mobile comprising a plurality of columns 2.
  • These slots 10 are arranged to, in certain positions of the mobile, allow the introduction of a feeler or a pin into a recess 5 in a transverse direction T substantially normal to the profile P and substantially parallel to the reference surface 1, and to in other positions of the mobile, stopping a feeler or a pin on a transverse stopping surface 81, 201, 202 of a column 2.
  • the transverse direction T is a radial coming from the axis of the mobile.
  • At least one column 2 comprises at least one intermediate transverse stop surface 81, which is arranged to constitute an abutment bearing surface for a feeler or a pin and allow partial introduction of a feeler or a pin in the thickness of slot 10, and which is located, in a transverse direction T, between the geometric envelopes of two end transverse surfaces 201, 202, which delimit column 2 transversely.
  • each column 2 which comprises at least one intermediate transverse stop surface 81 has a variable thickness in the transverse direction T, and comprises at least one projection 4, which is arranged to hold a feeler, a finger, or a pin 3, or similar, of a clockwork mechanism arranged to cooperate with the selector mechanism 100, the projection 4 comprising the intermediate stop surface 81 and a front stop surface 82 in the direction of the profile P.
  • the projection 4 is arranged to retain a feeler or a pin in at least one direction in the direction of the profile P. More particularly, the projection 4 is arranged to retain a feeler or a pin in a single direction in the direction of the P profile.
  • a column 2 comprising a projection 4 comprises at least two opposite projections 4, each arranged to retain a feeler or a pin in a direction opposite to the other.
  • This embodiment with at least one projection provided in at least one column, more particularly each column, is advantageous because it is particularly compact.
  • the selector mechanism 100 in a different way, for example by splitting the columns, certain so-called outer columns performing the outer stop function on a first side, referred to as outer, of the selector mechanism 100, and other so-called inner columns performing the inner stop function on a second, so-called inner side of the selector mechanism 100; the geometry of these interior columns is then adapted to ensure the functionality of such projections, and, for example, the interior columns can each consist of several pins 88, 89, one of which 88 comprises an intermediate stop surface 81 and the the other 89 a front stop surface 82, and optionally an end transverse surface 202.
  • the projections can be, depending on the desired functionality, located inside the profile as in the variant illustrated by the figure 1 , or outside the profile as in the variant illustrated by the figure 11 , or on either side of the profile as in the variant illustrated by the figure 12 .
  • the projections 4 can still be stepped, as seen on the figure 13 , where successive projections 41 and 42 are each arranged to stop a mobile in a particular position.
  • this selector mechanism 100 is thus arranged to define several transverse positions for the introduction of an operating or control member: frontal stop of abutment on one of the end transverse surfaces 201, 202, complete transverse travel through the clearance 5, partial transverse travel limited to abutment on a surface of the projection 4.
  • frontal stop of abutment on one of the end transverse surfaces 201, 202 complete transverse travel through the clearance 5, partial transverse travel limited to abutment on a surface of the projection 4.
  • the mobile extends along a closed profile P, and the slots 10 extend between an outer envelope geometric surface defined by the outer end transverse surfaces 201 of the columns 2, and an inner envelope geometric surface defined by the inner extreme transverse surfaces 202 of the columns 2.
  • the closed profile P is circular, and the outer envelope geometric surface and the inner envelope geometric surface are cylindrical and coaxial.
  • the profile P is closed, and at least one projection 4 is inside the mobile. More particularly, each projection 4 is inside the mobile.
  • the profile P is closed, and at least one projection 4 is outside the mobile. More particularly, each projection 4 is outside the mobile.
  • At least one column 2 comprises at least one bearing 11 in its height, in an axial direction DA perpendicular to the base surface 1.
  • the bearing 11 is limited by an intermediate stop surface 61 and/or 62 according to the invention.
  • this variant schematized on the figure 14 , requires a greater height, which is not always possible.
  • the invention also relates to a chronograph mechanism 400 comprising at least one such selector mechanism 100, controlled by a control means 200 that can be operated by the user. More particularly, this chronograph mechanism 500 comprises a disengagement control for the minute counter 22, which makes it possible to disengage from the minute wheel set 40 the driving finger of the 360 minute counter, as seen on the figure 4 , while on the figure 2 and 3 this drive finger 360 meshes with the wolf-tooth wheel 41 of the minute counter 40.
  • This disengagement control of the minute counter 22 carries a pin 3 which is arranged to, depending on the position of the mobile, in a starting position, hereinafter referred to as "start", corresponding to the running of the chronograph, remaining at least partially in a clearance 5 between two columns 2, or in a stop position corresponding to stoppage of the chronograph cooperate in support with a projection 4, or in a reset position for resetting the chronograph to support on an extreme transverse surface 201, 202, d a column 2.
  • the clearance 5 between two neighboring columns 2 is delimited by edge surfaces 6 and 7 of these two columns 2.
  • the beak 21 of the clutch lever 210 is arranged to cooperate, or in abutment on an outer extreme transverse surface 201 of column 2, or in the position of insertion in a recess 5.
  • This chronograph mechanism 400 illustrated by the figures, comprises such a selector mechanism 100, here a column wheel, whose profile P is circular, and comprises the constituents listed according to the nomenclature at the end of this description.
  • the invention also relates to a timepiece 1000, in particular a watch, comprising at least one timepiece movement 500, and at least one chronograph mechanism 400 comprising at least one selector mechanism 100 according to the invention, controlled by means control 200 accessible to the user.
  • the invention makes it possible to work on a single column level, which is advantageous for the overall thickness of the mechanism in which the selector mechanism 100 according to the invention is incorporated, and by using the available space, in particular the interior of the columns 2, as visible on the figure 1 , for specific features.
