  • the clutch wheel may consist of a circular board having an external toothing arranged to cooperate with the driving or driven wheel, said circular board being surmounted by a concentric ring of smaller diameter, presenting the internal toothing, said clutch wheel being mounted free to rotate about its axis.
  • the positioning means comprise a jumper having adjusting means.
  • each satellite may comprise a first and a second coaxial wheel and integral in rotation, the first wheel being arranged to mesh with the internal toothing of the clutch wheel and the second wheel being arranged to mesh with one or the other of the driving and driven wheels in the engaged position, each of said first and second wheels being provided with a set of teeth defined by a head diameter and a pitch diameter, the head diameter of the second wheel being substantially equal to the pitch diameter of the first wheel.
  • the clutch wheel may consist of a circular board mounted to rotate about its axis, and surmounted by a ring having the internal toothing.

  • the present invention also relates to a timepiece comprising a movement as described above. Brief description of the drawings
  • the clutch device 1 is intended to connect a driving wheel 2 to a driven wheel 3.
  • the driving wheel 2 is for example the seconds wheel of a watch movement
  • the driven wheel 3 is a chronograph wheel carrying a needle 3a for displaying the timed time.
  • Said device 1 comprises firstly a clutch wheel 4 consisting of a circular board 5 having an external toothing 5a, surmounted by a concentric ring 6, of smaller diameter, and having an internal toothing 6a.
  • the circular board 5 and the concentric ring 6 are integral.
  • the clutch wheel 4 is mounted free to rotate about a central axis 7 fixed to the frame 8 of the clockwork movement, for example between two plates.
  • the clutch wheel may comprise a circular board integral with the axis of the clutch wheel, surmounted by a ring having the internal toothing.
  • the outer toothing 5a of the clutch wheel 4 previously described is replaced by connecting means integral with the axis of the clutch wheel, and arranged to cooperate with a suitable driving gear.
  • These connecting means may for example comprise a pinion integral with the axis of the clutch wheel.
  • a planet carrier 10 coaxial with the central axis 7 of the clutch wheel 4.
  • the planet carrier 10 is rotatably mounted around this central axis 7.
  • the planet carrier 10 comprises a base 10a and an upper portion 10b, between which three satellites 11a, 11b, 11c are mounted free to rotate around three axes 12 distributed regularly around the planet carrier 10. It is obvious that the satellites can also not be distributed regularly.
  • the upper part 10b of the planet carrier 10 is generally circular in shape and has, regularly distributed around its periphery, six actuating fingers 15 constituting means for actuating the planet carrier 10, and arranged to make it pass from the one to the other of the two positions disengaged / engaged.
  • said control means comprise a control lever 17 mounted to move on the support and carrying an index 17a movable about an axis 18.
  • the end 19 of the index 17a is arranged to cooperate successively with the actuating fingers 15 of the planet carrier 10 and driving it in rotation so as to rotate it about the central axis 7 by 1/6 of a turn at each loading of the control lever, corresponding to the passage to one either of the two positions disengaged / engaged.
  • a return spring (not shown) is provided to return the control lever to the initial position, abutting against an actuating finger 15, waiting for a new bias.
  • a spring 21 is provided to maintain the support of the control index 17a on the planet carrier 10.
  • control lever 17 is connected to a control member (not shown), arranged to operate on demand said control lever 17.
  • This control member is for example of the push-stop type, traditionally mounted on the middle of the box and used in the chronograph mechanisms. It is obvious that other control means can be used.
  • the positioning jumper 22 comprises a head 22a provided with two inclined planes, each of them resting on one of two positioning fingers 15 consecutive when the planet carrier 10 occupies one or the other of the two disengaged / engaged positions.
  • the position of the jumper 22 and the spring 21 can be adjusted by adjustment means, for example eccentrics, not shown in the drawing.
  • the different elements of the clutch device 1 are sized and arranged so that the satellites 11a, 11b, 11c cooperate with the internal gear 6a of the clutch wheel 4.
  • the satellites 11a, 11b, 11c must, in addition, be thick enough to also cooperate with the driven wheel 3 in the engaged position, once the clutch device 1 mounted in a clockwork movement.
  • the external toothing 5a of the clutch wheel 4 is dimensioned so as to mesh with the driving wheel 2 once the clutch device 1 has been mounted.
  • the satellites 11a, 11b, 11c and the actuating fingers 15 are arranged around the planet carrier 10 so that, once the clutch device 1 is mounted in a clockwork movement, from the disengaged position, the 1/6 turn rotation of one of the actuating fingers 15 pushed by the index 17a of the control lever 17 causes the rotation 1/6 turn of the planet carrier 10 and its satellites 11a, 11b, 11c.
  • the satellite 11a which cooperates with the driven wheel 3 following the displacement of the actuating finger 15a, as shown in FIG. figure 3 .
  • the number of satellites can vary and that it is possible to provide for example 1, 2, 3, 4 satellites or more.
  • the skilled person can calculate the number and shape of teeth, the number and dimensions of satellites, and the dimensions of the different wheels, depending on the desired dimensions for this type of mechanism.
  • three satellites, each having 20 teeth can be provided with a driven wheel of 60 teeth, an internal toothing of 60 teeth, an external toothing of 80 teeth and a driving wheel of 80 teeth.
  • the jumper 22 can be fixed on the frame by means for moving it slightly to change its position and thus adjust this alignment.
  • the control lever 17 is positioned against a stop secured to the frame so that the index 17a is in the vicinity of one of the actuating fingers 15.
  • the driving wheel 2 drives the clutch wheel 4 by meshing with the external toothing 5a.
  • the satellites 11a, 11b, 11c rotate on themselves by meshing with the internal toothing 6a of the clutch wheel 4.
  • the clutch device 1 When the chronograph is not used, the clutch device 1 is in the disengaged position, in accordance with the Figures 2 and 3 . In this position, none of the satellites 11a, 11b, 11c meshes with the driving wheel 3.
  • the driven wheel 3 In the engaged position, the driven wheel 3 is driven by the satellite 11a itself driven by the internal toothing 6a of the clutch wheel 4.
  • the user presses again on the control member which actuates the control lever 17.
  • Its index 17a presses the actuating finger 15b to move it 1/6 of a turn in the direction counterclockwise and thus move 1/6 turn the satellite carrier 10 in the counterclockwise direction so that the satellite 11a disengages the driven wheel 3.
  • the clutch device 1 then returns to the disengaged position.
  • the control lever 17 then resumes its initial position in the vicinity of the next actuating finger 15c.
  • the satellite 11b has in turn placed close to the driven wheel 3 to be ready to go into the engaged position at the next actuation of the control lever 17.
  • the clutch device according to the invention is advantageous in that it makes it possible to avoid a jump back of the driven wheel and therefore of the needle carried by this wheel at the time of clutch, that the driven wheel is synchronized or not with the driving wheel.
  • the driven wheel 3 comprises twenty-one teeth, as well as the internal toothing 6a of the wheel clutch, while the satellite 11 comprises seven teeth.
  • the driven wheel 3 is synchronized with the drive wheel and with the internal toothing 6a of the clutch wheel.
  • the arrows F1, F2, F3 and F4 respectively illustrate the rotational movement of the planet carrier, the satellite, the clutch wheel and the driven wheel.
  • the satellite 11 When the satellite 11 arrives near the driven wheel 3 to move into the engaged position, it is driven on the one hand by a counterclockwise rotation movement due to the displacement of the planet carrier and on the other hand by a rotational movement in the clockwise direction meshing with the internal toothing 6a of the clutch wheel in response to the displacement imposed by the carrier. Due to this compound movement, the tooth 30 of the satellite 11, which is closest to the driven wheel 3 intersects the head circle of the teeth of the driven wheel 3 at an angle close to 90 °. There is therefore virtually no relative tangential movement of the toothing of the satellite relative to that of the driven wheel. Thus, the driven wheel 3 can not be driven back at the time of clutch.
  • the principle is the same when the driven wheel 3 is not synchronized with the driving wheel and the internal toothing 6a of the clutch wheel. More particularly with reference to the figure 7 when the satellite 11 arrives near the driven wheel 3 to move into the engaged position, the tooth of the satellite 11 which is closest to the driven wheel 3, driven by the compound rotation movement described above, will enter tangentially into the teeth of the driven wheel and press against the tooth of the driven wheel 3 by imparting to it a rotational movement in the same direction of rotation as that of the driven wheel 3 once engaged. Thus, the driven wheel 3 can not not be dragged back at the time of clutch. Therefore, the needle 3a carried by the driven wheel 3, and more particularly the chronograph hand can not jump back.
  • the clutch device according to the invention is also advantageous in that it eliminates any adjustment of the penetration of the various wheels required in traditional chronograph mechanisms.
  • the conditions of penetration of the satellite teeth into the driven wheel can be adjusted by changing the structure of the satellite.
  • An exemplary embodiment is shown on the figure 8 .
  • the satellites 11 each respectively comprise a first wheel 40 and a second wheel 41 coaxial and rotationally fixed about their respective axis 12, the first wheel 40 being arranged to mesh with the internal toothing 6a of the clutch wheel 4 and the second wheel 41 being arranged to be able to mesh with the driven wheel 3.
  • the other elements of the clutch device are identical to those described above.
  • the first wheel 40 and the second wheel 41 are each provided with a set of teeth defined by a head diameter and a pitch diameter, the head diameter of the second wheel 41 being substantially equal to the pitch diameter of the first wheel 40.
  • This characteristic makes it possible to give the teeth of the second wheel 41 a trajectory such that the heads of these teeth have a substantially radial trajectory when they mesh with the driven wheel 3, which makes it possible to obtain greater precision in the movements during the penetration into the driven wheel.
  • the leading and driven wheel positions were reversed.
  • the driving wheel 2 which is arranged to cooperate with the second wheel 41 of the satellite 11 when the device is in the engaged position
  • the driven wheel 3 which cooperates with the external toothing 5a of the wheel of clutch 4. Therefore, in the disengaged position, only the driving wheel 2 rotates.
  • the first wheel 40 of the satellite 11 is rotated only in the engaged position, to drive in turn the clutch wheel 4 by meshing with the internal toothing 6a, then the driven wheel 3 by meshing with the toothing outside 5a.
  • the mechanism for actuating the planet carrier 10 to move from one to the other of the engaged / disengaged positions by means of a control lever is identical to that described above.
  • the clutch wheel consists of a circular board mounted to rotate about its axis, and surmounted by a ring having the internal toothing.
  • the carrier comprises satellites, and the outer toothing of the clutch wheel is replaced by the toothing of the satellite which, in the engaged position, is at the level of the driving wheel to cooperate with it.
  • the satellite meshing with the driving wheel then causes the rotation of the clutch wheel by meshing with the internal toothing of the clutch wheel.
  • the satellite then meshes with the gear wheel meshing with the internal toothing of the clutch wheel.
  • each satellite may comprise a first and a second coaxial wheel and integral in rotation, the first wheel being arranged to mesh with the internal toothing of the clutch wheel and the second wheel being arranged to be able to mesh with one or the other.
  • other wheels driving and driven in the engaged position, each of said first and second wheels being provided with a set of teeth defined by a head diameter and a pitch diameter, the head diameter of the second wheel being substantially equal to the pitch diameter of the first first wheel.
  • the clutch device according to the invention is described here as a clutch device in a chronograph mechanism, but it is obvious that it can be used in any mechanical application requiring the connection to the request of a wheel driving with a driven wheel.
