Definitions

  • the invention relates to a unidirectional wheel watchmaker, arranged to rotate in a single direction in cooperation with a movable ratchet in a ratchet chamber, said mobile having at least one pawl arranged to be secured to rotate with said unidirectional wheel. .
  • the invention also relates to a winding mechanism of at least one pair of watch cylinders, including such a mobile for winding each barrel.
  • the invention also relates to a watch comprising at least one such mechanism, and / or at least one such mobile.
  • the invention relates to the field of watchmaking mechanisms, including power supply of timepieces, including watches.
  • the energy reloading mechanisms of mechanical timepieces are often bulky, and occupy a large volume of the timepiece, especially in the direction of thickness.
  • the ratchet mechanisms include delicate springs to assemble or handle after-sales, and space-consuming.
  • the invention proposes to develop a space-saving mechanism, particularly in terms of thickness, for recharging the energy of a watch.
  • the invention relates to a unidirectional wheel watchmaker according to claim 1.
  • the invention also relates to a winding mechanism of at least one pair of watch cylinders, including such a mobile for winding each barrel.
  • the invention also relates to a watch comprising at least one such mechanism, and / or at least one such mobile.
  • the invention relates to a unidirectional wheel clock mobile 1 1, arranged to rotate in a single direction in cooperation with a movable ratchet 3 in a ratchet chamber 30 shown in dotted lines in the figures.
  • This mobile 1 comprises at least one pawl 4, which is arranged to be secured in rotation with the unidirectional wheel 2.
  • the pawl 4 constitutes a one-piece component comprising at least one spring arm 6, at the end 9 forming a head, and of which, on a first side, at least one spout 5 is arranged to cooperate directly with the toothing of a ratchet 3 in a service position in which the spring arm 6 is free.
  • the elasticity of the spring arm 6 is adjusted to allow the hooking or unhooking of the first hook 7 relative to the second hook 8, under the action of an operator or a manipulator, either by a maximum elongation of the spring arm 6 by a length greater than that of the extended position, either by a tilting of the end 9 or both by maximum elongation of the spring arm 6 and tilting of the end 9.
  • this pawl 4 comprises, at the right of each spout 5, which is movable substantially radially relative to a pawl axis A, a recess 50 which is arranged to allow the complete radial disengagement of the spout 5 with a Ratchet 3
  • this pawl 4 comprises a substantially annular portion 40 which comprises, at each end 9, a first clearance 70 arranged to accommodate a first arm 71 of a first hook 7. And each arm-spring 6 has at its end 9 a second clearance 80 arranged to accommodate a second arm 81 of a second hook 8.
  • the clearance 50 is located in the substantially annular portion 40 of the pawl 4, and is arranged to house the spring arm 6 with the head including the spout 5 and the first hook 7, and this clearance comprises a surface of support 49, substantially radial in the variant of the figures, against which bears a distal end face 69 of this head.
  • This arrangement makes it possible to limit the deformation of the leaf spring in the ratchet drive movements.
  • this ratchet 3 has a symmetry of order N with respect to a pawl axis A, the number N being the number of leaf springs 6 that includes the pawl 4.
  • this pawl 4 is integral with the unidirectional wheel 2, and may in particular be made of a micro-machinable material, such as silicon or the like, by a "LIGA” or “MEMS” method or the like.
  • the pawl 4 comprises gripping means 90, which are arranged for their simultaneous cooperation with a tool 200 having a symmetry of order N with respect to a tool axis arranged to be centered on the axis of pawl A, and, to simultaneously separate the pawl axis A beaks 5 beyond the right of way of the ratchet 3 and the ratchet chamber 30, in particular to carry out an adjustment or a maintenance operation.
  • the figure 7 shows such a tool 200 having bosses 201 arranged to push the leaf spring 6, and bear on these gripping means 90, here constituted by a wedge that forms the end of the leaf spring 6 under the spout 5.
  • the invention also relates to a mechanism 100 for reassembly of at least one pair of watch barrels 110, comprising, for the reassembly of each barrel 110, such a mobile 1, the pawl 4 is arranged to cooperate with a ratchet 3 for driving a shaft that includes the barrel 110.
  • the mobiles 1 are symmetrical with respect to each other and coplanar.
  • the mechanism 100 comprising driving means comprising a rod 101, and a gear train comprising, without limitation, a set of wheels 102, 103, 104, 105, and an inverter 106, arranged together to drive each unidirectional wheel 2 in a direction different, so as to always drive a ratchet 3, regardless of the direction of operation of the drive means.
  • the rod 101 makes it possible to raise either barrel 110 irrespective of the direction of rotation of the rod 101, without the need for disengagement: in one direction the pawl 4 raises the barrel, and in the other sense the same ratchet 4 disengages the same barrel 110.
  • this mechanism 100 comprises such mobiles 1, and such a removable tool 200, having a symmetry of order N with respect to a tool axis arranged to be centered on the pawl axis A and to simultaneously discard pawl axis Has the beaks 5 beyond the grip of the ratchet 3 and the ratchet chamber 30 of each mobile 1 to carry out an adjustment or a maintenance operation.
  • the invention also relates to a watch 1000 comprising at least one such mechanism 100, or / and at least one such mobile 1.
