Definitions
- the present invention relates to a large watch movement power reserve and more particularly a mechanism comprising a device motor comprising several barrels, a manual winding cog of this motor device and possibly a gear train for power reserve indication.
- One of the aims of the present invention is to provide a motor device for a watch movement, especially for a pocket watch or a wristwatch, which has a footprint compatible with a caliber of pocket watch or wrist watch and which allows obtaining a reserve walking more than a week, preferably between 8 and 10 days.
- Another object of the present invention is to provide this motor device with a cog of indication of the power reserve.
- Another object of the invention is to allow reassembly of the device motor above the value corresponding to the maximum indication of reserve of works without distorting this indication.
- Yet another object is to provide a provision in the motor device so that the user can manually wind the motor device beyond its maximum winding without damage to it.
- the subject of the present invention is a watch movement, in particular for wristwatch and pocket watch, with a large reserve of step with a motor device wound up using a winding train and resulting in a gear train which is distinguished by the characteristics set out in claim 1.
- the attached drawing illustrates schematically and by way of example a shape of the motor device and its winding train, as well as a form of execution of a power reserve indication cog.
- Figure 1 illustrates in section a part of the motor device according to the invention.
- Figure 2 illustrates in section a part of the motor device and its cog to wind up.
- FIG. 3 illustrates in section the engine device and the gear train for indicating power reserve.
- Figure 4 is a section on a smaller scale illustrating the motor device and the final train.
- Figures 5 and 6 are plan views of the engine and the train power reserve indication.
- Figure 7 is a plan view of the watch provided with the mechanisms according to the invention.
- the timepiece is a wristwatch comprising a movement housed in a box 1 provided with a crown of winder 2 and whose dial 3 includes a time display, a small second, a date display and a power reserve display comprising a graduation 4, bearing the numbers 0 to 8 indicating in days the reserve of step, and a needle 5 cooperating with this graduation 4.
- the timepiece movement according to the present invention comprises a large power reserve, between eight and ten days, in all cases exceeding one week. In this way the user does not have to wind his watch once a week and the engine torque is stable enough to ensure precision in running required by chronometers.
- This watch movement with a large power reserve includes a motor mechanism comprising four barrels, a manual winding gear train and, in the illustrated embodiment, a cog of power reserve indication.
- the driving force behind this watch movement has two groups of two superimposed barrels arranged side by side.
- the first group of superimposed barrels has two cages of barrels mounted and pivoting on the same axis 6, i.e. a first cage of barrel 7 and a second barrel cage 8.
- the first barrel cage 7 houses a first barrel spring 9 whose inner end is integral with the core 6 ' while the outer end is integral with a friction flange which can slide in the first barrel cage when the friction force exceeds one preset value.
- the first barrel cage 7 is provided with teeth external engagement with a barrel pawl 10 subjected to the action of a spring ratchet 11, so that the first barrel cage can only rotate in one only sense.
- the second barrel cage 8 contains a second barrel spring 12 whose inner end is integral with the core 6 ', while its end outer is secured to the second barrel cage 8.
- the second barrel cage 8 has an engaging external toothing with barrel return 13.
- the second group of two superimposed barrels has an axis 14 on which are pivotally mounted a third barrel cage 15 and a fourth barrel cage 16.
- the third barrel cage 15 has teeth external engagement with the barrel return 13 and contains a third spring of barrel 17 whose external end is integral with the third barrel cage 15 and whose internal end is integral with the core 14 '.
- the fourth barrel cage 16 contains a fourth barrel spring 18 whose internal end is secured to the core 14 ', while the outer end is secured to this fourth barrel cage 16.
- This fourth barrel cage 16 comprises a external teeth.
- the present movement includes a gear train comprising, in the example illustrated, an intermediate mobile 19 meshing with the external toothing of the fourth barrel cage 16 and with the pinion 20 of a large mobile medium whose wheel 21 is engaged with the pinion of a mobile of medium 22 of the watch movement.
- the rest of the watch movement will not described here, this being conventional.
- this motor device lies in the fact that it is composed of two groups of two concentric and superimposed barrels, the second and the third barrels being engaged by means of a barrel return, the spring of the first barrel 7 being equipped with a sliding flange spring to avoid any overvoltage in the cogs, while the other three barrels 8,15,16 are fitted with springs identical to those of a manual winding watch.
- the four barrels are connected in series so as to add up their duration of disarming while delivering constant torque, the four springs having identical or substantially identical characteristics.
- the friction torque between the flange of the first spring 9 and the first barrel cage 7 is higher the torque delivered by the springs 9, 12, 17 and 18 in the fully assembled state.
- This motor device drives the watch movement through of the finishing train, it is armed with a manual winding train.
- This manual winding train includes a first winding mobile whose wheel 23 is engaged with the teeth of the first barrel cage 7 and the pinion 24 meshes with a crown wheel 25.
- This crown wheel 25 is engaged with a winding pinion 26 when the winding rod 27 is in depressed winding position.
- the motor device is reassembled by the crown of winder 2 through the winding cog 27,26,25,24 and 23 to the first barrel 7 which, connected by its spring 9 to the core 6 ′, arms the second barrel 8,12 then, by means of barrel reference 13 goes up the third barrel 15,17, then through the core 14 'the fourth barrel 16,18.
- the motor device drives through the cage 16 of the fourth barrel the gear train through the intermediate mobile 19.
- the winding cog includes a first mobile 23.24 multiplier winder allowing faster reassembly of the four barrels.
- the motor device is still equipped a power reserve indication cog illustrated in section, plus particularly in Figure 3.
- This power reserve indication cog operating the hand 5 of display 4.5 of the power reserve includes a first reference indication of power reserve 30 engaged with the teeth of the first barrel cage 7 and meshing with a second power reserve indication reference 31 angularly secured to an axis 32.
- This axis 32 carries a pinion 33 and serves as a pivot to a differential wheel 34 engaged with the teeth of the fourth cage of barrel 16.
- This axis also serves as a pivot for a differential mobile comprising a pinion 35 and a wheel 36.
- a satellite mobile is pivoted idly on an axis 37 integral of the differential wheel 34. This satellite mobile comprises a pinion 38 in engagement with the wheel 36 of the differential wheel and a wheel 39 in engagement with the pinion 33 of axis 32.
- the pinion 35 of the differential mobile is engaged with the wheel 40 of a first mobile power reserve indication, the pinion 41 of which meshes with the wheel 42 of a second power reserve indication mobile, the pinion 43 of which is in taken with the wheel 44 of an indicator mobile 46, the axis 45 of which carries the needle 5 of the power reserve display.
- the wheel 44 of the indicator mobile is friction mounted on the mobile indicator 45.46.
- the indicator mobile 45,46 carries a pin 47 cooperating with a fixed stop 48.
- the needle 5 of the power reserve display is next to the largest digit of the graduation 4 indicating that the power reserve is at its maximum.
- This maximum indication of the power reserve display corresponds to the complete reassembly of the motor device.
- the needle 5 reaches the end of the stroke and the indicator mobile 46 is maintained in this angular position by the pin 47 and the stop 48.
- the wheel 44 moves angularly under the action of the power reserve indication cog by compared to the indicator mobile, thanks to its friction coupling, i.e. up to when the motor device is fully reassembled and the flange of the first spring 9 of the first barrel slides in the first barrel cage 7.
- the cage of the first barrel 7 causes the first return power reserve 30, the second power reserve reference 31 and therefore the pinion 33, the satellite mobile 38.39, and the pinion 35 which drives the mobile indicator 46 carrying the needle 5 via the two indication mobiles power reserve 40.41 and 42.43, until this hand 5 indicates the maximum power reserve, the indicator mobile then being immobilized by the pin 47 coming into contact with the stop 48.
- the user can continue to reassemble the motor device, the wheel 44 being able to slide frictionally on the indicator mobile 46, until the four springs of barrel are fully armed and the flange of the first barrel spring 9 slides on the first barrel cage 7.
- the indicator mobile 46 and its wheel 44 are driven by the fourth barrel cage 16, the differential wheel 34, the satellite 38.39, the differential mobile 35.36 and power reserve indication mobiles 40.41 and 42.43.
- Needle 5 therefore arrives at look at the zero of the graduation 4 before the motor device is completely disarmed.
- the drive device could include two groups of three concentric barrels, the third of which would drive the fourth using the barrel reference 13.
- the number of barrels in each group depends on the height available in the movement. The more the number of barrels mounted in The larger the series, the greater the total power reserve of the engine.
- the number of power reserve indication references 40.41; 42.43 might be different in other constructions.
- Most of the cog power reserve indication is that it has a drive from of the first barrel of the first group and a second drive from the last barrel of the second group driving an indicator mobile by through a differential mobile and a satellite in proportion to the differential speed between the first barrel and the last barrel of the engine.
- the indicator mobile 46 and its wheel 44 are connected by a friction clutch and the first barrel spring is connected to the first barrel cage by a friction flange as is, for example, the case in barrels fitted with self-winding movements.
