  • value it is generally understood a number, a calendar information (like the calendar, the day of the week or the month) and also the selection of a function or an application among a plurality of functions or applications, this list is not exhaustive.
  • the invention particularly relates to the drive mechanism of an analog indicator with periodic or intermittent displacement and the impact resistance means of this indicator, as well as the precise positioning of the indicator in each display position of a plurality discrete display positions planned.
  • a trailing mechanism For training a calendar indicator, in particular a date ring, three types of mechanism are essentially known: a trailing mechanism, a conventional semi-instantaneous mechanism and an instantaneous mechanism.
  • the trailing mechanism 2 is provided to drive a date ring 4 provided with an internal toothing 6.
  • This trailing mechanism comprises a Maltese cross 8 and an actuating wheel 12 of the latter.
  • the Maltese cross has six branches 9 and is integral with a coaxial pinion 10 which meshes with the toothing 6 of the date ring.
  • the pinion 10 comprises six teeth.
  • the number of branches of the Maltese cross and the number of teeth of the pinion are given here as a non-limiting example.
  • such a mechanism is also known with a four-pointed Maltese cross and an eight-toothed pinion.
  • the ratio between the number of teeth and the number of branches is an integer.
  • the actuating wheel 12 comprises two drive pins 16, 17 and a locking member 14 which cooperates with the branches 9 to lock the Maltese cross in stable positions between two successive drives performed respectively by the two pins.
  • This operating mobile is rotated for example by a pinion 20.
  • the operation of a Maltese cross system is well known, it will not be described here in more detail.
  • the dragging mechanism described above is characterized by a gear with little play, or without play, and the absence of jumper.
  • the drive function and the positioning function of the date ring in its display positions are both performed by the pinion associated with the Maltese cross.
  • the anti-shock function is performed by the Maltese cross system, the locking member 14 easily performing this function.
  • the manufacture of a watch movement with such a mechanism is expensive because it is necessary to minimize the machining and mounting tolerances (manufacturing tolerances) of this mechanism and the date ring to ensure accurate positioning of this ring in its display positions, for example a precise centering of each date in the window of a dial designed for the watch movement.
  • the conventional semi-instantaneous drive mechanism comprises a date ring drive wheel generally provided with a finger or two fingers which periodically penetrates into the toothing of the ring to drive it from one end to the other. display position to a following.
  • the gaps between the teeth of this toothing are generally relatively wide, especially to allow each finger to enter and out of the toothing of the ring without risk of blockage; this especially because of manufacturing tolerances and centering of the date ring.
  • the drive wheel can not provide the positioning function of the ring.
  • it can not provide an anti-shock function because generally there is no meshing between the toothing and the finger, respectively the two fingers on certain angular ranges of the drive wheel.
  • a jumper spring also called jumper
  • jumper which is inserted between two successive teeth of the teeth of the ring.
  • the ring is rotated by a finger of the drive wheel and the tip of the tooth downstream of the jumper raises the jumper up to that the top of the saltire is in support against the top of this tooth. Then, the jumper exerts a tangential force on the rear flank of the concerned tooth to go to take its next rest position.
  • the jumper quickly drives the ring of the dates in rotation to its next display position, the finger of the drive wheel continuing its rotation at a lower speed than the ring and therefore ceasing to exercise a couple of strength on this ring.
  • the space between the teeth is large enough so that the tooth following that pushed by a finger does not abut against this finger inserted in the teeth of the ring.
  • a major drawback of this semi-instantaneous mechanism comes from the fact that the anti-shock function is performed by the jumper, which must therefore press on the date ring with a large force to be able to exert a sufficient locking torque in case of shock.
  • the drive mechanism must provide at each date of passage a significant engine torque to overcome the positioning torque of the jumper; which requires a lot energy and a mechanism capable of providing such a motor torque at the tooth of the ring date.
  • the object of the present invention is to solve the problems and disadvantages of the drive mechanisms of an analogue indicator with periodic or intermittent displacement of the prior art, in particular a date ring.
  • the subject of the present invention is a watch movement equipped with an analogue display device for a piece of information whose value varies periodically or intermittently, this analog display device comprising on the one hand an indicator of this information provided with a first gear and on the other hand, a periodic or intermittent drive mechanism of the indicator.
  • This drive mechanism is formed by an irreversible transmission system comprising a second toothing which meshes with the first toothing.
  • the display device further comprises a locator for positioning the indicator generating a positioning force on the first toothing, this positioning force being sufficient to precisely position this indicator in a plurality of discrete display positions, but insufficient for provide a shockproof function for the indicator.
  • the tangential clearance between the first and second sets of teeth is large enough so that these first and second sets of teeth do not touch when the indicator is in any display position of the plurality of discrete display positions and the irreversible transmission system is in a predefined corresponding position.
  • This transmission system irreversible has an anti-shock function for the indicator via meshing of the first and second teeth at least when this indicator is in any display position of the plurality of discrete display positions and the irreversible transmission system is in said predefined corresponding position.
  • periodic training is meant training which occurs only periodically, i.e. training takes place periodically during a limited period of time and no training occurs between the limited time intervals.
  • 'intermittent drive' is understood a discontinuous drive which stops and resumes depending on the control of the intermittent drive mechanism without this drive necessarily intervenes at regular intervals.
  • the drive mechanism defines a mechanism resembling a semi-instantaneous mechanism with one or more drive fingers of the integral indicator (s) of a Maltese cross, this or these finger (s) forming the second toothing mentioned above.
  • the positioning jumper is also generally used for driving the indicator in a second phase of the passage of the indicator from a display position to a next display position.
  • the drive function of the indicator at least in a first phase of the passage of the indicator from a display position to a next display position and the shockproof function are provided by the system.
  • irreversible transmission which is capable to exercise a very important blocking force.
  • the positioning function is not ensured by this irreversible transmission system as in the prior art, but by a positioning jumper exerting a sufficient force for this function but much lower than a usual minimum locking force of the transmission. indicator in case of shock.
  • the watch movement 24 is equipped with an analog date display device, which is a periodic variation information, and various functions F1, F2, etc. which can be selected by a user of a watch equipped with the watch movement.
  • This analog display device comprises a ring 26 provided with a first toothing 28 and a drive mechanism 30.
  • On the ring 26 are printed the various calendars '1' to '31' and the designation of the various possible functions.
  • Each date and each function defines a discrete display position of the ring 26 through in particular a window provided in a dial mounted on the watch movement 24.
  • the drive is periodic for the date and intermittent for the selection of one of the plurality of possible functions.
  • the drive mechanism 30 is formed by a Maltese cross system defining an irreversible transmission system. It comprises a drive wheel 32 with a Maltese cross 34 surmounted by a pinion 36, the latter having a second toothing 38 which meshes with the first toothing 28.
  • the driving mechanism further comprises an actuating wheel 40 driven by a pinion 46 which is itself rotated by an electromagnetic motor not shown.
  • the actuating wheel comprises two pins 41 and 42 aligned on a diameter of this actuating wheel and a locking member 44 centered on this axis of rotation. The pins are arranged for to penetrate between the branches of the Maltese cross and to allow the driving of the wheel 32 and thus of the independent date ring.
  • the locking member 44 serves to lock the wheel 32 by its positioning in any curved end of the branches of the Maltese cross.
  • the Maltese cross system thus defines an irreversible transmission, since the actuating wheel can drive the drive wheel in rotation, but not vice versa. Whatever the angular position of the actuating wheel, a force torque transmitted by the drive wheel to this actuating wheel will cause the rotation of the latter at most over a small angular distance.
  • a self-locking drive mechanism because by design it blocks the transmission of a force torque and thus a rotation in the opposite direction to that which is provided.
  • the locking member 44 is substantially aligned with the end of a branch of the Maltese cross (as shown in FIGS.
  • the first toothing 28 and the second toothing 38 have between them a tangential clearance, substantially equal to J1 + J2 as represented on FIG. Figure 2B .
  • This tangential clearance is provided sufficiently large so that the first and second sets of teeth do not touch each other when the ring 26 is in any display position of the plurality of discrete display positions mentioned above and the Maltese cross system. is in a corresponding predefined position, preferably as Figures 2A and 2B .
  • the first and second teeth are always in a situation of meshing. Thus, an untimely jump of the independent date ring is never possible in case of shock.
  • the tooth 48 will always be in a space 50 between two adjacent teeth 51 and 52 of the toothing 28 once the completed training and the Maltese cross system again in a non-drive position provided for the plurality of discrete display positions.
  • the pinion 36 remains stationary if a large force torque is exerted on it by the ring 26.
  • This ring can therefore only move in the game. said tangential when in any display position of the plurality of discrete display positions.
  • the Maltese cross system thus has an anti-shock function for the ring 26 through the meshing of the first and second teeth.
  • anti-shock function is intended to prevent the mechanism from breaking or being damaged in the event of an impact, but to prevent the indicator from permanently changing its discrete display position under the effect of a shock to which the watch must be able to be subjected without breaking (According to NIHS 91-10, 91-20, 91-30 and other standards).
  • the display device further comprises a jumper 56 for positioning this ring.
  • the jumper also called jump spring, is formed of an arm 58, having a positioning tooth 60 at one end and pivoting about an axis at the other end, and a spring 62 which exerts a force on the arm so as to generate a positioning force on the first toothing 28.
  • this positioning force has a tangential component acting on the toothing of the ring so as to bring the ring back to its display position in the absence of a discreet display position change, either to bring the ring in a terminal phase in another display position provided during an actuation of the drive device of the ring.
  • the spring 62 is a curved elastic blade or rod with a portion in a groove 64 and the other portion bearing against the rear lateral face of the arm 58.
  • the positioning force is sufficient to precisely position the ring 26 in a plurality of discrete display positions but is insufficient to provide a shockproof function for this ring.
  • the positioning force is therefore less than the usual minimum locking force of the ring in the event of an impact, so as to make it possible to drive the ring in rotation with a relatively low torque force and thus to minimize the energy required to move from one display position to another.
  • the positioning force is on the one hand greater than a maximum friction force exerted by the watch movement on the ring 26 and on the other hand less than triple this maximum friction force.
  • a conventional brass date ring with a diameter of 20 mm requires a torque of approximately 60 ⁇ Nm to overcome the static friction force on the ring with the movement posed to dish.
  • the jumper must in this example be able to exert a torque of blocking force of about 2000 ⁇ Nm.
  • this shockproof couple will be lower, for example about 800 .mu.m.
  • the present invention makes it possible to greatly reduce the torque exerted by the jumper on the ring and therefore the necessary motor torque to be transmitted by the drive mechanism 30. In particular, it is possible to reduce the reduction ratio in this drive mechanism.
  • the tangential clearance between the first and second sets of teeth is greater than or substantially equal to twice the cumulative production tolerances involved in the gear formed by the ring 26 and the Maltese cross wheel 32 at the first level. and second teeth 28 and 38.
  • the clearance between the first and second set of teeth is less than the maximum distance over which the jumper spaced apart from a stable rest position, corresponding to a display position, by displacement of the indicator is capable of to return this indicator in this stable rest position by the positioning force that it exerts on the toothing of the indicator.
  • it is the half-game plus cumulative manufacturing tolerances involved in the gear, formed by the indicator and the irreversible transmission system at the first and second teeth, which is less than the maximum distance defined. above.
  • the theoretical position of the second toothing of the irreversible transmission system, for the discrete display positions of the indicator is substantially centered in the first toothing of the indicator; that is to say that the clearance is substantially evenly distributed on one side and the other of the tooth or teeth of the second toothing inserted into the first toothing of the indicator, as c is the case Figure 2B .
  • the jumper may also have a certain tolerance as to the display positions that it defines by its stable rest positions in the first toothing. This tolerance is advantageously added to the cumulative production tolerances involved in the aforementioned gear to define the game to be provided in the variants presented above.
  • the Jumper position can be adjusted after mounting the indicator, so that the discrete display positions are predefined very accurately and the jumper positioning tolerance can be neglected.
  • the drive mechanism 64 of a date ring 26A comprises a drive wheel 66 on which are fixed two pins 68 and 69, which define a second toothing in the gear formed by the ring 26A and the wheel 66.
  • This wheel is driven by a pinion 70 associated or coupled to the rotor of an electromagnetic motor.
  • the two pins are aligned on a diameter of the wheel 66.
  • Figures 3A and 3B which corresponds to the position of the wheel 66 provided in the discrete display positions of the date ring, these two pins provide a total locking of the date ring. Indeed, a force torque applied by the ring on the wheel 66 can not rotate this wheel, which thus forms with its two pins an irreversible transmission system.
  • the two pins are not cylindrical, but have a substantially semicircular section to allow a relatively large clearance between the first toothing 28A and the second toothing formed of these two pins while ensuring a gear that does not do not block.
  • each pin can alternatively out of a gap of the teeth 28A and then enter again into a space of this toothing without butter against the top of a tooth.
  • a jumper spring similar to that of the first embodiment, is provided for accurately positioning the date ring in a plurality of discrete display positions.
  • the stator is arranged to generate a positioning torque applied to the permanent magnet rotor of this motor, which can be increased by a short circuit of the coil, particularly in the case of a motor. a Lavet motor.
  • This positioning torque keeps the rotor in at least one stable rest position (position taken in the absence of power supply).
  • the motor can be configured so that the positioning torque of the rotor transmitted at the wheel meshing with the indicator defines a locking torque that is greater than the maximum force torque that can exert the indicator on this wheel, in particular when 'a shock.
  • the reduction of the kinematic chain of the drive mechanism is provided relatively large so that the blocking force is sufficiently high. It will be noted that the locking torque obtained depends not only on the positioning torque and the reduction factor of the kinematic chain, but also friction losses in this driveline.
