Definitions

  • the present invention relates to a timepiece non-circular movement provided with a mechanism chronograph including rockers and a wheel columns.
  • Wristwatch movements with a mechanism are generally circular.
  • the reason main thing is that the chronograph mechanism occupies a large area.
  • surface reduction is generally between 10% and 15% compared to the surface of the circle in which this movement of form is registered.
  • This loss of surface to house the chronograph mechanism is added to the surface occupied by the exhaust mechanism, representing approximately 30% of the remaining surface, which must be left free so as not to interfere with the setting of the shows.
  • the purpose of the present invention is to provide a solution to this problem.
  • the present invention relates to a associated timepiece with non-circular movement to a chronograph mechanism as defined by the claim 1.
  • the advantage of the proposed solution is to allow reduce the space occupied by the chronograph mechanism and thus offer the possibility of carrying out in particular a shaped wristwatch provided with such a mechanism.
  • the timepiece movement not shaped circular with which the chronograph mechanism is associated is a movement with an additional reduction mobile between the barrel and the center wheel also called large medium, allowing the barrel to rotate more slowly and thus accommodate a motor spring capable of to run the movement for about 10 days so as to ensure a useful walking period of 8 days.
  • the movement is still provided with a power reserve indicator mechanism.
  • the chronograph mechanism object of the invention is completely integrated into the form movement, that is to say that all of the organs that compose it are directly mounted on the various cog bridges without intermediate support allowing optimal use space both on the surface and at height.
  • FIG. 1 shows in particular a chronograph mechanism, a control rocker 1 pivotally mounted around a bolt 1a mounted in the barrel bridge B and one end of which 1b is intended to be connected to a single pusher (not shown) coaxial with the winding stem T.
  • the end 1b of flip-flop 1 could also be opposite "2 hours".
  • the other end of this control lever 1 ends with a ratchet 2 in taken with ratchet teeth 4a ( Figure 3) of a wheel columns 4.
  • a return spring r 1 tends to bring the control lever 1 back to a rest position illustrated in FIG. 1, against a stop 1d working with the edge of an oval opening 1c, thus delimiting two limit positions.
  • Another return spring r 2 tends to keep the pawl 2 constantly engaged with the ratchet teeth 4a.
  • This column wheel 4 is selectively in direct contact with all the rockers of the chronograph mechanism.
  • rocker 5 of the reset hammers carrying two hammers 5a, 5b and pivoted around an axis 5c secured to the barrel bridge B.
  • This rocker 5 is engaged with a return spring r 5 which presses it constantly towards the column wheel 4.
  • Another rocker constitutes a brake 6 constantly pushed against the column wheel 4 by an elastic arm 6a came from stamping with brake 6 and bearing against a stop 6c.
  • This brake 6 is pivotally mounted around a screw scope 6b screwed into the barrel bridge B.
  • a third lever is the clutch lever 10 which has a semicircular movable pivot opening 10a pivotally mounted around a circular surface 14a of a pivoting plate 14, itself mounted pivoting around a screw 14b screwed into a bridge S of the seconds wheel 15a (figure 11).
  • the angular position of this pivoting plate 14 is adjustable around the axis of this screw 14b using an eccentric 13.
  • the semi-circular mobile pivoting opening 10a has a bearing which opens onto the upper face of the rocker 10. This range is used to hold the rocker 10 between the second bridge S and a staff surrounding the circular surface 14b of the pivoting plate 14, opening onto the underside of this pivoting plate 14 and adjusting to the complementary scope of the semi-circular movable pivot opening 10a of the toggle 10.
  • the clutch lever 10 has two upper parts 10s and below 10i assembled by a 10v screw ( Figure 11) between which a clutch wheel 16 is swivel mounted. This clutch wheel 16 is constantly in engagement with a driving wheel 15 integral with the axis of the seconds wheel 15a.
  • the seconds bridge S is higher than the bridge of the gear train R.
  • the height difference is chosen so as to allow the driving wheel 15 and the clutch lever 10 of pass over the bridge of the gear train R. Thanks to this arrangement and to the tilting pivot system clutch 10 along an axis coaxial with that of the wheel seconds 15a and of the driving wheel 15, the excess thickness due to the chronograph mechanism is reduced to a minimum. Only the axis of the seconds wheel 15a carrying the driving wheel requires a modification of the watch movement, all the rest of the chronograph mechanism lying outside the watch movement does not generate any changes of this movement.
  • a return spring r 10 ( Figure 1) pushes the clutch lever 10 clockwise around the circular pivot surface 14, so that the end of this clutch lever 10 is constantly in contact with the column wheel 4.
  • a last lever, called inter-counter lever 21 is pivotally mounted around a bearing screw 21a.
  • a return spring r 21 pushes this rocker 21 clockwise and presses one of its ends against the column wheel 4 ( Figure 3).
  • the other end of this lever carries an intermediate wheel 18 of the minute counter which is constantly engaged with a wheel 8 of the minute counter whose pivot axis 8a (FIG. 10) crosses the entire movement to exit from the dial side of the movement to carry a minute counter hand (not shown).
  • This wheel 8 of the minute counter still carries a heart-shaped cam 9 (FIG. 3) intended to cooperate with the arm 5 a of the hammer 5 for resetting to zero during the resetting of the minute counter.
  • a chronograph wheel 19 is still pivoted in the center of movement and its axis crosses all movement for exit the dial side of the movement to carry a needle (not shown) of the second counter.
  • This wheel of chronograph 19 has a drive finger 17 on the wheel intermediate 18 of the minute counter ( Figures 5 and 9) driving the wheel 8 of this counter at each rotation, that is to say once a minute.
  • This chronograph wheel also carries a heart-shaped reset cam 20 ( Figure 3) intended to cooperate with the arm 5b of the hammer reset 5.
  • a jumper spring 3 is engaged with the toothing ratchet 4a of the column wheel and a jumper spring 7 is in gear with the wheel 8 of the minute counter.
  • the penetration of the clutch wheel 16 carried by the clutch lever 10 is adjustable by means of a stop 11 constituted by an eccentric, serving to limit pivoting of the clutch lever 10 clockwise of a watch, thus making it possible to adjust the penetration of the toothing of the clutch wheel into that of the chronograph 19.
  • Another eccentric stopper 12 serves to limit pivoting of the intermediate lever 21 clockwise of a watch and therefore the penetration of the drive finger 17 in the teeth of the intermediate wheel 18.
  • Figure 2 shows the cog of the watch movement.
  • this movement includes an additional mobile 24 between the toothing of barrel 22 containing the mainspring (not shown) and the pinion 23a of the center wheel 23.
  • This mobile additional 24 increases the reduction between the barrel 22 and the center wheel 23, so that the barrel 22 rotates more slowly than in a conventional movement, which increases the power reserve of the watch of about two days for a classic watch at about ten days in this case, or 8 useful days.
  • the cog of the power reserve indicator is basically on the dial side of the movement ( Figures 13 and 14).
  • this train has a gear 37 engaged on the one hand with the ratchet 36 of the barrel 22 and on the other hand with a differential wheel 38, the shaft 38a of which crosses movement and has a square 38b engaged with a reference 31 meshing with a satellite 32 pivotally mounted on a rod 30a of a crown 30 carrying the differential.
  • This crown 30 is engaged with a reference 29 which meshes with a pinion 28a of a wheel 28 coaxial with the barrel 22 and which is in kinematic connection with the barrel 22 thanks to a double pinion 39 meshing simultaneously with the teeth of barrel 22 and that of wheel 28.
  • the pinion 32a of the satellite 32 meshes with an intermediate wheel 33 which meshes with a drive wheel 34 whose pinion 34a meshes with a toothed sector 35 bearing the power reserve indicator (not shown) which moves at an angle of 90 ° for example, between the armament and disarming the mainspring contained in barrel 22.
  • Figure 13 indicates by arrows the directions of rotation the different moving parts of the indicator cog power reserve during the winding phase of the barrel.
  • the mobiles without arrows correspond to those which are fixed, i.e. barrel 22, double pinion 39, the wheel 28 coaxial with the barrel 22, the reference 29 and the differential crown 30.
  • Figure 14 indicates by arrows the directions of rotation respective of the reserve indicator cogs during the disarming phase of the barrel spring.
  • the mobiles that remain stationary during this phase do not have arrows, it is ratchet 36, reference 37, of the differential wheel 38 and of the driving gear satellite 31 secured to the differential wheel 38.
  • Figures 3 to 8 show the only chronograph mechanism during the different phases of a complete cycle of operation.
  • Figure 3 shows this mechanism reset zero.
  • the arrows indicate which organs are movement and the respective directions of movement. All mechanism parts are at rest except for the wheel drive 15 and the clutch wheel 16 which are in kinematic link with the cog 22-27 of the movement of the shows.
  • Figure 4 illustrates the start-up phase of the mechanism chronograph.
  • the arrows show which are the moving parts and their respective directions of movement.
  • This start-up is controlled by flip-flop 1 following pressure exerted on its end adjacent to the winding stem T ( Figure 1).
  • This pressure rotates column wheel 4 clockwise clockwise and this rotation causes the movement of rocker 5 in the direction of the arrows and the release of the hammers 5a, 5b, as well as the displacement of the clutch scales 10 and inter counter 21 in the directions respective arrows.
  • Figure 5 shows the chronograph running.
  • the levers in engagement with the columns of the column wheel 4 are in the same positions as before, and all the wheels of the chronograph mechanism are moving in the respective directions indicated by the arrows.
  • the rocker of control 1 is returned to the rest position.
  • they are trained step by step by finger 17 of the chronograph wheel 19, once per revolution of this wheel 19, that is to say once per minute.
  • FIG. 7 shows the chronograph stopped, that is to say that with respect to FIG. 6, the pressure on the control lever 1 has ceased to be exerted, so that it has returned to the rest position under the pressure of the return spring r 1 , thus putting the pawl 2 in the ready position for actuating the column wheel in a new step of 20 °.
  • the brake 6 retains the chronograph wheel 19 in the position in which the chronograph mechanism has been stopped, allowing the time measured by this mechanism to be read between its start and stop.
  • FIG. 3 shows the respective positions of the members of the chronograph mechanism after the reset, once the control lever 1 has been returned to the rest position by the return spring r 1 .
