Definitions
- a movement of this type is described in the document EP 0'501'190 . It includes a basic module and a chronograph module.
- the first frame, the base module, carries a time base and a set of mobiles forming the gear wheels and finishing, and the date mechanism, including a first date ring.
- the second frame of the complementary module carries a second set of mobiles, including a second date ring, thus ensuring the display of a time function.
- the first ring drives the second ring through the connecting mobile.
- the latter comprises, for this purpose, first and second wheels which meshing respectively with the first and second date rings.
- This mobile link carries, at its ends, pivots engaged one in the frame of the basic module, the other in that of the chronograph module. This implies that the frame of the complementary module extends above the mobile link. This results in an extra thickness that is detrimental to the aesthetics of the movement.
- One of the frames is provided with a slot made in its thickness, in which is engaged the shaft of the connecting mobile.
- a retaining member positions the connecting mobile on its frame.
- the connecting mobile is a sliding pinion which can have two extreme positions occupied in the direction of rotation of the rod and which makes it possible to correct two different functions, by driving components arranged on the complementary module.
- this sliding pinion is mounted on a part of the mechanism of time setting. There is nothing to determine how it is positioned.
- An object of the present invention is to overcome these disadvantages.
- the movement according to the invention further comprises a retaining member cooperating with the connecting mobile and arranged to prevent its movement inside the slot, while allowing its rotation.
- the connecting mobile is held in the slot, can rotate freely, but can not move laterally, and ensures its return function by the wheels arranged at its ends, without having to provide extra thickness to ensure its pivoting.
- the slot is made in the frame of the complementary module. It is extended by a clearance dimensioned so as to engage at least one of the wheels of the connecting mobile.
- the retaining member is formed of a first mobile of the base module, and a second mobile of the complementary module.
- the mobiles forming the retaining member are advantageously coaxial and mesh with the wheels of the connecting wheel in areas above and below the slot of the frame in which the shaft of the connecting wheel rotates.
- the mobiles forming the retaining member can thus constitute the first and second date rings. These rings are provided with an internal toothing, while the slot is oriented radially with reference to the axis of rotation of these rings.
- the movement shown in the drawing comprises a first module 10, basic, comprising a frame 12, which carries mobiles, including a date ring 14, which comprises a first ring 14a, a second ring 14b and a connecting member 14c.
- the ring 14a is driven by a date mechanism well known to those skilled in the art, which has not been shown.
- the ring 14b is provided with an internal toothing 14d.
- the base module 10 carries a complementary module 16, the characteristics of which will be specified below, disposed on the dial side of the movement and which comprises a frame 18.
- the latter carries, in particular, a date ring 20 arranged on the dial side and provided with an internal toothing 20a, coaxial with the ring 14.
- the frame 18, advantageously brass coated with a protective layer, for example a browning, comprises a board 21 provided with a slot 22, radially oriented with reference to the pivot axis of the rings 14 and 20. It forms , in its part farthest from the center of the movement, a cylindrical clearance 22a, housed between the date rings 14 and 20.
- the shaft 24c is of cylindrical shape.
- This mobile 24 can be made in one piece Vietnameselletée or by assembly of one or both wheels, for example brass, driven on the steel shaft 24c provided with its bearings 24d and 24e.
- the slot 22 has a width slightly greater than the diameter of the shaft 24c.
- the thickness of the board 21 is slightly less than the distance between the lands 24d and 24e.
- the diameter of at least one of the wheels 24a and 24b is smaller than the dimensions of the clearance 22a. In this way, the mobile 24 can be put in place and removed by engaging one of the wheels in the recess 22a, then be laterally displaced to freely rotate while being in abutment with the slot 22.
- the rings 14 and 20 When the mobile 24 is in abutment in the slot 22, and the rings 14 and 20 in place, they are respectively engaged with the wheels 24a and 24b. They mesh in areas above and below the slot 22, the rings 14 and 20 covering the clearance 22a. That is to say that the rings 14 and 20 prevent the mobile 24 from moving radially in the slot 22. They therefore provide a stop function, thus ensuring the positioning of the mobile 24 on the frame 18.
- FIGS. 2, 3a and 3b show, respectively from above and in section, the module as partially shown in FIGS. 1 and 2.
- the frame 18 In its center, the frame 18 comprises an opening 18a in which is housed a pinion 26 driven on a roadway 27, itself mounted frictionally on a center wheel 28 carried by the frame 12 of the base module 10.
- the latter and the pinion 30 are concentric to a mobile 33 seconds pivoting in the frame 18 of the module 16 and driven by a wheel driven on the mobile average of the finishing train. It is held axially by a bridge spring 34 screwed into the frame 18.
- the complementary module 16 carries, in addition, means for displaying the time relative to a second time zone 36, comprising, arranged concentrically, a first mobile of hours 38 and a second mobile hour 40, respectively performing a lap and two laps per day, and a minute gear 42.
- Figure 4 shows more precisely and exploded the structure of the mobile 40. It comprises a first wheel 40a provided with two guns 40b and 40c extending on either side of the board of the wheel 40a. A pinion 40d is driven on the barrel 40b. A retaining ring 40e is attached to the end of the barrel 40b. Between the board of the wheel 40a and the ring 40e is disposed a wheel 40f, at the same level as the pinion 40d, provided with resilient arms cooperating with the toothing of the pinion 40d. In addition, a 40g wolf wheel is driven on the barrel 40c.
- a second timer wheel 44 meshes with the pinion 26 and drives the minute gear 42.
- the timer wheel 44 carries a pinion 44a which meshes with the hour wheel 40a.
- the reduction between the hours wheels 40a and 38 is by a mobile 46 which allows a gear ratio of two.
- the complementary module 16 thus makes it possible to display the time of a second time zone, by means of an hour hand 48, a minute hand 50 and a day-night disc 52 comprising two equal ranges 52a and 52b.
- the hour hand 48 is carried by the barrel 40c of the mobile 40, the minute hand by the pinion 42 and the disc 52 by the wheel 38.
- the hour hand 48 moves over the disc 52, it is easy to know if the time displayed corresponds to the day and the night. Indeed, insofar as the hour hand 48 is placed so that it is at the interface of the beaches day and night when it displays six hours, it sweeps in twelve hours, six hours to six o'clock the day beach and the night beach. Thus, since the hour hand is at four o'clock and in the beach 52a, which appears in dark, or carries for example a moon or stars, it is easy to deduce that it is four o'clock morning.
- the time setting can be carried out in a conventional manner, by a rod not shown in the drawing, which causes, by means well known to those skilled in the art, the pinion 26.
- the second time zone is corrected by means of a pusher acting, by a lever not referenced, on the control pawl, which turns the mobiles 38 and 40a and, with them, the hour hand 48 and the disc 52.
- the connecting mobile 24 could be positioned in the slot 22 by a specific member, for example a bridge rigidly fixed to the board 21 provided with the slot 22.
- the module 16 can also ensure the display of any type of complementary function, for example a chronograph function, a moon phase, or a large date display.
- the clearance 22a could also be eliminated and the slot 22 extend to the periphery of the board 21.
- the mobiles of the basic module and the complementary module cooperating with the mobile link may also not be annular. The quality of the positioning of the latter is however less good.
