Definitions

  • the present invention relates to a watch movement comprising a rotary member for an external manual control connected by at least one connecting member to at least one element of the movement and capable of being rotated in two opposite directions.
  • Rotating members of the aforementioned type are well known and are most often in the form of a crown that the user can rotate in two opposite directions to control one or two features, such as setting the time or date. winding a barrel.
  • the present invention aims to improve the known crowns and allow to drive safely and independently at least two functions with the ring in the same axial position pulled or not pulled.
  • the movement according to the invention is characterized for this purpose by the fact that it comprises at least one selection device associated with the rotary member and arranged to occupy at least two different positions comprising a first position in which it authorizes the rotation of the connecting member in a first direction and makes it impossible to rotate the connecting member in a second direction, and a second position in which it makes impossible the rotation of the connecting member in the first direction and allows the rotation of the connecting member in the second direction.
  • the direction of rotation of the crown is secure because the selection device only allows the direction of rotation of the crown chosen by the user by its prior action on the selection device.
  • the selection device comprises a locking device arranged to lock in said first position the rotation of the rotary member and the connecting member in said second direction and so as to lock in said second position rotates the rotary member and the connecting member in said first direction.
  • the selection device is arranged to occupy an additional position in which it makes impossible the rotation of the connecting member in both directions of rotation.
  • the locking device comprises at least two locking members capable of cooperating with at least one toothing integral with the rotary member and at least one control member arranged so as to establish or interrupt the contact of said toothing with the one or other of the locking members.
  • the two locking members are constituted by a first and second spring blades arranged to cooperate by their free end with the toothing so as to oppose for the first spring blade to a rotation of the organ rotating in the second direction and to allow a rotation of this rotary member in the first direction, and so as to oppose for the second leaf rotates the rotary member in the first direction and to allow a rotation of this rotating member in the second direction, said control member being provided with at least one piece arranged to move one or the other spring blades of the toothing according to the position of the control member selected by a user .
  • control member is constituted by a rocker rotatably mounted around a ring constituting said rotary member, said rocker being provided with a protuberance in the form of a semi-cylindrical sector intended to cooperate with one or the other blades spring to separate them from the toothing according to the position of the latch chosen by the user.
  • the two locking members are constituted by blockers mounted sliding in cylinders each biased by a spring towards a rest position, and each comprising at least one projection capable of cooperating with a toothing integral with the rotary member.
  • these blockers being mounted on at least one movable control part movable to put one and / or the other of the blockers in contact with said toothing to lock the rotary member in one or the other both directions of rotation.
  • This variant allows a very high build strength and reliable operation.
  • the first embodiment comprises a movement 10 with a rotary member 11, such as a ring 12, intended to serve as an external manual control connected by at least one connecting member 14 to at least an element of the movement and capable of being rotated in two opposite directions.
  • This crown can thus serve as a winding and / or organ for controlling functions such as time setting, time zones, the date, the moon phase, a repetition or a ring, etc.
  • the rotary member 11 is provided with a selection device 13 for actuating particular functions of the movement and comprising at least one locking device 15 arranged to occupy at least two different positions comprising a first position in which it blocks the rotation of the ring 12 in a first counterclockwise direction and allows the rotation of the rotary member in a second clockwise direction, and a second position in which it blocks the rotation of the crown in the second clockwise direction and allows its rotation in the first anticlockwise direction.
  • a middle part 20 of the movement housing comprises a bore 21 into which a tube to be chased 22 is driven and glued.
  • the latter is traversed by a rod 23 serving as connecting member 14 secured to the ring 12 by driving-gluing or screwing.
  • the locking device 15 comprises a spring ring 24 mounted on a support tube 25 which is screwed onto the tube to be driven 22.
  • the spring ring 24 has two leaf springs 26, 27 protruding on its periphery to cooperate with an internal toothing 28 of the crown 12.
  • the locking device 15 is further provided with a control lever 30 rotatably mounted around the ring 12 on the tube to be driven 22 and the support tube 25.
  • This rocker 30 has a protuberance 31 in the form of a semi-circular sector. cylindrical disposed between the spring ring 24 and the internal toothing 28 of the ring 12.
  • This control lever 30 comprises a stop 34 intended to cooperate with two recesses 35, 36 provided in the middle part 20 to limit the rotation of the latch 30 to 180 °.
  • the protrusion 31 is interposed between the leaf spring 26 and the internal toothing 28 to move the leaf spring 26 of the toothing, which allows a rotation of the ring 12 in a clockwise direction.
  • the leaf spring 27, which is oriented in a substantially tangential direction of the spring ring 24 enters at its end between the teeth of the toothing 28 to oppose a rotation of the ring 12 in a counterclockwise direction to the figure 4.
  • Two ball pawls 38, 39 are mounted in the middle part 20 (FIG. 6) and cooperate with two recesses 40, 41 provided on the control lever 30 to hold the latter in this position.
  • control lever When it is desired to control another function, the control lever is rotated 180 ° in a clockwise direction (FIG 4, 5) to occupy a second position illustrated in FIG.
  • the control lever 30 is again held in position by the two ball pawls 38, 39.
  • the protuberance 31 does not separate the spring blade 26 or the spring blade 27 from the toothing so that the ring 12 is locked in both sense of rotation.
  • the protrusion 31 could occupy a larger sector, for example 210 °, so that it allows to separate the two spring blades 26 and 27 of the toothing 28 in said intermediate position to allow rotations clockwise and counterclockwise.
  • the locking device 15 is provided with a seal 42 disposed between a central portion 43 of the ring 12 and the support tube 25.
  • Markings 44 (FIG 4, 5) on the flip-flop 30 or the middle 20 could make it possible to visualize the direction in which the crown can be rotated by the user and / or the function that it will be possible to control.
  • the blocking device 15 allows in particular a dual control function with the ring in the same drawn position, for example to control either a time zone function when the ring is turned in one direction, an update function when the crown is turned in the other direction.
  • the selection and locking devices are independent of the movement and its features. They may also be adapted to select more than two possible functions by pulling the ring axially on two or more predetermined longitudinal positions.
  • the selection device 13 also comprises a locking device 15, but instead of presenting a rotary control lever, the locking device comprises a sliding control part 50 mounted on the middle part of the movement.
  • the ring 12 is extended by a cylindrical portion 51 having a toothing 52 and connected to a connecting rod 23.
  • a seal 53 seals the crown.
