    Description TECHNICAL FIELD [0001] The present invention relates to the field of watchmaking. It relates, more particularly, a timepiece comprising a programmable trigger mechanism. This mechanism comprises a power source arranged to store energy and restore it when triggering.
    Most commonly, the mechanisms that we want to program, that is to say, set, the trigger time, are alarm-type mechanisms, which, at a set time, cause a ring that alert the user, for example to wake him up or to give him an appointment. But we can also perform other functions that can be programmed, such as the beginning of a PLC type animation, or moving a display mobile.
    STATE OF THE ART [0003] In the example of alarm clocks or bell watches, the sound of the alarm is obtained by striking a stamp with a hammer. This hammer must strike the stamp with sufficient speed, in order to put the stamp in vibration. The contact of the stamp with the hammer must also be almost instantaneous, so as not to disturb the vibrations of the timbre. To do this, the hammer generally acts under the action of an anchor, cooperating with a star. star by a specific barrel or barrel of movement, causes the alternating tilting of the anchor and the striking of the hammer.
    The operation of the ring is energy consuming. It is therefore quite rare that the striking mechanism is powered by the barrel movement. Otherwise, it is still necessary to provide complex security to prevent the ringing does not stop the movement, if the power reserve is insufficient when triggering the ringing.
    This is why, in general, the waking mechanism benefits from its own barrel. However, it is not easy for the user, when setting the time of his ring, to know if the barrel is armed or sufficiently armed. It would be necessary to have a power reserve indicator specific to the striking barrel, which would greatly complicate the mechanism.
    The present invention aims to overcome this disadvantage by ensuring that the programmable trigger mechanism is always able to operate, since a trigger has been provided, but without detriment to the power reserve of the source d main energy of the movement.
    Disclosure of the invention [0007] More specifically, the invention relates to a timepiece comprising a programmable triggering mechanism, said mechanism comprising: a power source arranged to store energy and to restore it when triggering, - a kinematic armature chain arranged to arm the energy source under the action of a user, - a programming system arranged to be actuated by a user to program the trigger.
    According to the invention, the programming system is further arranged to drive the drive kinematic chain simultaneously to a trigger programming operation.
    Advantageously, the timepiece comprises a locking system arranged to maintain the power source in the armed position between the programming operation and the trigger.
    The invention also relates to a programmable trigger striking mechanism, comprising at least one movably mounted hammer with reference to a stamp to strike it. The mechanism is arranged to occupy: - a state of rest, in which the hammer is in the vicinity of the stamp, - a state of arming, in which the hammer is removed from the stamp, against the action of the hammer spring, and - a ringing state, in which the hammer is free to strike the stamp under the action of the hammer spring, which is armed.
    The invention also relates to a method of operation of a programmable trigger mechanism, comprising a power source arranged to store energy and to restore it at the time of tripping, the operating method comprising a step of trigger programming, a wait step between programming and triggering, and a triggering step. According to the invention, the arming step of the energy source is performed simultaneously with the programming step, and the energy source remains armed during the waiting step.
    [0012] Other features are also claimed in a dependent manner.
    BRIEF DESCRIPTION OF THE DRAWINGS [0013] Other details of the invention will appear more clearly on reading the description which follows, made with reference to the appended drawing in which: FIGS. 1 to 4 are top views of a timepiece according to one embodiment of the invention, in which the essential elements to the understanding of the description are represented; the different views correspond to successive stages of the operation of said timepiece, and FIGS. 5 and 6 more particularly illustrate parts of the timepiece.
    Embodiment of the Invention [0014] FIG. 1 a general view of an embodiment of a timepiece comprising a programmable trigger mechanism. By programmable trigger, it is meant that it is the moment of triggering, that is to say its time (in the general sense and not in the sense of the unit of time) of the trigger, which is adjustable. In the example described, the programmable trigger mechanism is a reminder system emitting a sound, but the person skilled in the art may apply it to other examples, such as when triggering a complete ring (alarm clock), an animation of the automaton type, a pivoting of a display or a deck, for example carrying a musical disc of the type used in certain bell watches or music boxes. Preferably, the invention is advantageously applicable when the triggered mechanism does not have a specifically dedicated barrel. The mechanism comprises a power source arranged to store energy and to restore it when triggering. In the example, the energy source is a hammer spring 10, arranged to propel a hammer 12 against a stamp 14 at the time of the ring, when it has been armed and it is released when triggering. More generally, the energy source is of elastic type and, as will be understood below, could also be a barrel.
    Armage [0015] The timepiece comprises a kinematic armature chain arranged to arm the energy source, under the action of a user.
    Thus, for example, a ring disposed at the end of a control rod of the winding stem type, is mounted to be accessible to a user from outside the timepiece. This part is of a type known to those skilled in the art and has not been represented. This control rod is kinematically connected with a mobile 20, better visible in FIG. 5, which has several functions which will appear as the present description. This mobile 20 is located on the axis of a functional assembly, which in this example is located at the center of the movement.
    The mobile 20 is kinematically connected to the kinematic chain of arming. This is formed by an armoring mobile 22, which comprises a pinion engaged with the mobile * and a wheel meshing with a triggering mobile 24. This triggering mobile 24 can take the form of a star, positioned by a jumper 26, and arranged to cooperate with a cam 28 secured to a first rake 30. The latter meshes with a second rake 31 that includes the hammer 12. The interaction between the wheel of the mobile armoring 22 and the mobile of trigger 24 is not de-modromic, so that depending on their respective position, they may not be in engagement with each other.
    Thus, the rotation of the mobile 20 by the control rod causes the rotation of the hammer 12. As will be better understood below, the timepiece is provided for the control rod does not cause the hammer 12 only in the direction of the points of a watch, with reference to the figure, which tends to move away from its stamp 14.
    The hammer 12 comprises a pin 32, with which cooperates the hammer spring 10. The hammer spring 10 is arranged to exert on the hammer 12 a force which tends to bring it closer to the stamp 14, Thus, when the kinematic chain armature drives the hammer 12, it pivots against the spring and therefore arm the latter.
    It will be noted here that the lug 32 is interposed between the hammer spring 10 and a strip 34, advantageously integrally with the spring, and which acts as a counter-spring, forming a support which aims to prevent the hammer 12 to hit the stamp 14 inadvertently, in case of shock experienced by the timepiece.
    The timepiece according to the invention further comprises a locking system arranged to maintain the power source in the armed position, pending release. In the proposed example, this locking system is obtained by the interaction between the triggering mobile 24 and the cam 28. At its periphery, the cam 28 has a notch 36. This is located in the zone with which it cooperates. the triggering mobile 24, when the spring 10 has reached a predefined arming state and considered sufficient, the notch 36 is shaped so as to obtain a wedge effect and a blockage * by the interaction of a branch of the movable trigger 24 with the notch 36. In this position, the legs of the trigger mobile 24 are no longer in the race of the mobile armature 22, which can thus turn in a vacuum if it is driven more.
    Thus, during the rotation of the mobile 20 by the control rod, the triggering mobile 24 is driven clockwise (FIG 2) and pushes the cam 28 in the counterclockwise direction, which has the effect of moving the hammer 12 of its stamp 14 by arming the hammer spring 10.
    These movements occur until a branch of the triggering mobile 24 takes position in the notch 36, defining a waiting position of the hammer 12, and now a state of winding of the spring. Triggering [0024] For triggering the ring, the timepiece comprises a tripping command 38, adapted to cooperate with the triggering mobile 24, and thus out of the notch 36 when the rake is kept armed.
    As can be better seen in FIG. 5, to govern the trigger, the timepiece comprises a trigger rocker 40. This is pivotally mounted on the mobile 20. The trigger rocker 40 can therefore also be rotated about the axis of rotation of the mobile 20, like a satellite of a differential. The reason for such an assembly of the rocker 40 on the mobile 20 will be understood later. This latch 40 comprises a spout 42, arranged so that a lateral support on the spout 42 causes pivoting of the rocker 40. It also comprises a rack 44 which, in the proposed construction is located in a plane different from that 42. On the mobile 20, a spring 46 is disposed in order to push the latch 40 towards the center of the mobile 20. The rocker solidly carries a pin 47, movable in a window 49 formed in the mobile 20, limiting the amplitude of displacement of tripping lever 40.
    The rack 44 is engaged with a connecting pinion 48. It is assembled coaxially with the tripping control 38, with a unidirectional link, torque limiting, in the direction of tripping.
    This unidirectional link is better visible in FIG. 6. The link pinion 48 is mounted integral with a tube 50, which also carries a ratchet pinion 52, integral with the tube 50. This ratchet pinion 52 is positioned in the plane of the tripping control 38, and takes place in the center of it, in an opening it contains. The ratchet gear 52 includes a wolf-tooth type toothing, allowing a unidirectional drive. The tripping control 38 comprises a board in which are formed elastic strips 54, defining pawls, and adapted to cooperate with the toothing of the ratchet pinion 52. Other types of snaps may also be used.
    Thus, a drive in rotation of the connecting pinion 48 in the counterclockwise direction (with reference to FIG 6), has the effect of causing the tripping control 38, while a driving of the connecting pinion 48 in a clockwise direction, will be capable of deforming the elastic lamellae 54, without causing the tripping control 38. This dissociation is obtained if the tripping control 38 is maintained with a force greater than the elastic force applied by the lamellae 54.
    The trigger control 38 comprises a rigid arm 56 which projects from the floor in the plane thereof. The rigid arm 56 has a flange oriented substantially radially and intended to bear against a stop 58. The rigid arm 56 is extended by a blade 60, preferably elastically deformable, and arranged so as to cooperate with a branch of the movable trigger 24, to rotate it.
    The timepiece further comprises a bridge 62 fixed on the plate and positioning in height the functional assembly formed by the mobile 20, the tripping control 38, the tube 50 and the connecting gears 48 and snap-fastening 52. The height positioning can be obtained by tabs 64 projecting above the board of the tripping control 38. This bridge 62 also forms the stop 58 against which can bear the rigid arm 56 of the tripping control 38 The stop 58 also comprises a flank, oriented essentially towards the center of the control, with which the rigid arm 56 can cooperate.
    Thus, when the mobile 20 is driven in the direction of clockwise with reference to FIG. 1, the trigger rocker 40 also pivots around the central axis of the mobile 20, and drives, via the rack 44, the connecting gear 48 in the direction of clockwise. The triggering control 38 may, if necessary, pivot in the direction of clockwise, solidarily to the connecting pinion 48, if the rigid arm 56 is not in contact with the side of the stop 58. If the arm rigid 56 is in abutment against the stop 58, the elastic lamellae 54 deform and unclip, allowing the link pinion 48 to rotate independently of the tripping control 38, which remains stationary.
    In contrast, an action on the nose 42 of the trigger rocker 40, to rotate it on its axis with reference to the mobile 20 against its spring 46, has the effect of driving the pinion 48 in counterclockwise, via the rack 44. The triggering control 38 also pivots counterclockwise, under the action of the resilient lamellae 54 against the teeth of the detent pinion. 52. As can be seen in fig. 4, the arm of the tripping control 38 leaves the contact of the side of the stop 58.
    The blade 60 then pushes the triggering mobile 24 which leaves the notch 36 of the cam, which triggers the programmable mechanism. The hammer 12 is then subjected only to the action of its spring 10, the cam 28 is no longer retained. The hammer spring 10 thus drives the hammer 12 against the stamp 14, thus bringing the cam 28 to its waiting position, by the connection between the rakes 30 and 31.
    Programming [0034] The timepiece according to the invention also comprises a programming system arranged to be actuated by a user to program said start time. In the example shown, the programming system is used to set the triggering time.
    As explained above, the triggering occurs by an action on the spout 42 of the trigger rocker 40, This action is obtained by a finger 70 driven by the movement, depending on the current time. This finger 70 can be worn by a wheel hours, performing a turn in 12h or 24h, depending on the setting possibilities that we want to give the user.
    The hour wheel is rotatably mounted coaxially with the mobile 20, so that its finger 70 is located in the plane of the trigger rocker 40 and adapted to cooperate with the nozzle 42. The spring 46 of the rocker maintains the nose 42 in the stroke of the finger 70, but the support of the pin 47 against the edge of the window 49 prevents the rocker is in permanent support against the periphery of the hour wheel. The induced friction is thus limited.
    Thus, the angular positioning of the tripping lever 40 relative to the finger 70, allows to define the moment of tripping. This angular positioning is defined by rotating the mobile 20. This rotation drive is obtained by means of the control rod, which also allows, as mentioned above, to perform the arming of the energy source ( the hammer spring 10 according to the example). The programming system is therefore arranged to drive the armature driveline simultaneously with a programming operation of the tripping time.
    The timepiece may advantageously comprise a display device synchronized with the programming system, to display the programmed start time.
    To do this a gear train 72 is engaged with the mobile 20 to drive a ring 74 surrounding the movement of the timepiece. This ring 74 may be integral with a flange mounted movably with reference to the dial and having an index, to indicate the time of adjustment by cooperating with the hours indicated on the dial or a specific time lapse, as desired of the manufacturer. Those skilled in the art can easily configure other types of display, for example in a sub-dial, possibly using a timer-type wheel to indicate the time and minutes of the trigger time.
    Operation [0040] Thus, in operation, a user will perform the setting of the trigger time: the ringing by acting on the control rod. In doing so, the mobile 20 is rotated in a clockwise direction (with reference to Fig. 1). The rotation of the mobile 20 angularly positions the nose 42 of the trigger rocker 40 with reference to the hour wheel, to program the time of tripping. Simultaneously, the rotation of the mobile 20 drives the kinematic chain of assembly (FIG 2), until the engagement of a branch of the triggering mobile 24 in the notch 36 (FIG 3), the reduction of the kinematic chain makes it possible to have sufficient arming and the locking of the cam 28 with a reduced stroke of the mobile 20, of the order of 15 °, allowing adjustment for the next half-hour with a wheel of the hours pivoting in 12 hours.
    If the locking position is not reached, the hammer spring 10 returns the cam 28 to its initial position of FIG. 1 and no ringing will occur, the hammer spring 10 not being released suddenly to propel the hammer. We can provide a desmodromic display device with the kinematic chain of arming, to display the state of the energy source, whether armed or not. For example, an integral pallet of the cam 28 may be provided, making it possible to produce this display. Thus, the user is warned if the spring is not armed.
    When the blocking position is reached, if the programming is not completed, the triggering mobile 24 is positioned by its jumper 26 out of the range of the armoring mobile 22.
    The arming is performed simultaneously with the triggering programming, using the torque provided by the user to arm the power source.
    When the finger 70 of the hour wheel, driven by the movement, reaches the level of the trigger rocker 40, it raises the latter, causing the triggering control 38 in the opposite direction of the clockwise and thus pivoting the triggering mobile 24 (FIG 4) by the action of the blade 60.
    The cam 28 being released, the hammer spring 10 can freely propel the hammer 12 against the stamp 14, to achieve the ringing. Under the action of the hammer spring 10, the cam 28 returns to its initial position (FIG 1). It is the same for the triggering mobile 24, under the action of its jumper 26.
    It can still be noted that if the trigger rocker 40 is raised while the energy source has not been previously armed, because there is no programmed trigger, the blade 60 of the command trigger 38 performs its stroke unladen because the triggering mobile 24 is not positioned in its race.
    Thus is proposed an embodiment of a timepiece comprising a programmable trigger mechanism, which is manually armed the energy source during the programming of the trigger. The mechanism takes energy from movement only when the finger 70 raises the trigger rocker 40, whether the spring 10 is armed or not. This sampling is small and limited in time; he does not preterite or little reserve power.
    Although the proposed example illustrates an alarm clock with a hammer 12 striking a blow during the trigger, the skilled person can use the teaching of the present application to propose various variants.

    Claims (11)
    [1]
    For example, the first rake 30 of the cam 28 could lead to a wheel having pallets, arranged to cooperate respectively with pallets of several hammers, to ring two notes or to strike several times the same stamped 14. [0050] The kinematic chain of arming could also be connected to the ratchet of a barrel, allowing to drive a ring gear, able to repeat several actuations of the hammer 12. It can provide a flywheel type regulator, located at l end of the ring gear. The locking system can be advantageously arranged to lock the ring gear and the ringing barrel, cooperating with the controller, because the torque exerted at this point of the ring gear is low. Furthermore, it could also be proposed to have an additional drive of the gear train, for example by coupling an additional drive on the mobile armoring 22. This training is done without causing the mobile 20, thanks to a friction connection between the mobile armoring 22 and the mobile 20, It could thus arm the power source without making a new setting, for example if we want to program the same time of trigger, 24 hours later, in the case where the hour wheel rotates in 24 hours. We can also note that the programming and the arming can be obtained by other types of actuators, such as through a rotating bezel for example, connected to the rotating flange. On the basis of the teaching above, the invention also relates to a programmable trigger striking mechanism, comprising at least one hammer 12 mounted movably with reference to a stamp 14 for striking it, said mechanism being arranged to occupy: - a state of rest, in which the hammer 12 is in the vicinity of the stamp 14, - a state of arming, in which the hammer 12 is moved away from the stamp 14, against the action of the hammer spring 10, - A ringing state, wherein the hammer 12 is free to hit the stamp 14 under the action of the hammer spring 10, which is armed. The state of rest is similar to what is known ring mechanisms of the state of the art, that is to say that the hammer spring 10 is not armed, and the position hammer 12 is secured by a counter-spring to prevent untimely strikes of the stamp 14.
