Definitions

  • the invention also relates to a timepiece comprising such an alarm mechanism.
  • the patent document EP 1 933 212 proposes to remedy the above problem by providing a timepiece comprising a striking mechanism and an isolation lever arranged to prevent any winding operation of the barrel during the striking.
  • a disadvantage of this previous solution is that the isolation lever does not prevent the strike from being triggered when the control rod of the strike winder is already kinematically connected to the rotary input/output member of the barrel. However, in such a case, the ringing cannot proceed normally. It may even block completely.
  • An aim of the present invention is to remedy the disadvantages of the prior art which have just been explained.
  • the present invention achieves this and other goals by providing a wake-up mechanism according to appended claim 1.
  • the alarm mechanism comprises means for keeping the kinematic connection between the control rod and the rotary input/output member of the barrel disengaged when the alarm mechanism is in the activated state.
  • the ringing mechanism is arranged not to trigger at the pre-programmed time when the alarm mechanism is in the deactivated state.
  • the alarm mechanism comprises an automatic device arranged to stop the ringing and to deactivate the alarm mechanism, when the driving of the ringing mechanism causes the disarming of the mainspring until the below a first predefined threshold value.
  • the wake-up mechanism comprises an insulator arranged to neutralize the activation function of the wake-up mechanism by the manually controlled mechanism, when the degree of winding of the mainspring is less than one second predefined threshold value, the second threshold value being higher than the first threshold value.
  • FIG. 1 is a plan view on the dial side of an alarm watch conforming to a particular embodiment of the invention.
  • the alarm watch shown will now be described by limiting itself to the essential aspects of the invention and leaving aside a large number of details which do not directly concern the invention.
  • the watch of the figure 1 has a winding crown (referenced 11) which protrudes from the middle of the watch approximately at 4 o'clock.
  • the crown 11 is arranged so as to allow the striking barrel to be reassembled by rotating it, in the pushed back position, in a clockwise direction. In the pulled out position, the winding crown 11 also allows the alarm time to be corrected.
  • the alarm time is displayed, in digital form, in two windows (referenced 3 and 5) which are arranged side by side in the dial at 12 o'clock.
  • the alarm clock shown in the figure 1 still includes a pusher (referenced 13) which protrudes from the caseband approximately at 2 o'clock.
  • This pusher is intended to allow manual operation of a mechanism arranged to alternately activate and deactivate the alarm mechanism of the watch.
  • This manually operated mechanism further preferably comprises an activation indicator member which is provided to indicate whether the wake-up mechanism is in the “activated” state or in the “deactivated” state.
  • an indicator member of this type is arranged to appear in a third small window of the dial (referenced 7). Window 7 is located at 12 o'clock between the first two windows 3 and 5 and the hour circle.
  • the alarm mechanism comprises a ringing mechanism (not shown) and a mainspring 15 ( Figure 2A ) arranged to disarm by driving the bell mechanism following triggering of the latter.
  • the mainspring 15 which is exclusively dedicated to actuating the bell is arranged in a barrel 14 which also includes a rotary input/output member.
  • the mainspring 15 drives the striking mechanism via the rotary input/output member and a gear train.
  • the rotary input/output member is constituted by a barrel shaft 79 which is secured to one of the ends of the mainspring and by a toothed wheel 17, the toothed wheel being rigidly fixed on the barrel shaft.
  • the barrel 14 also drives an inertia brake (not shown) which is designed to regulate its unwinding and therefore the frequency of the “ringing” shots.
  • the cog that connects the barrel to the inertia brake is called the “small cog”. This type of arrangement is known as such. It will therefore not be described further in the present description which deliberately leaves aside a large number of details which can be taken from the state of the art and which do not directly concern the invention.
  • ringing mechanisms in particular, a relevant description can be found for example in the book “Clockmaking theory” (pages 222-224 ).
  • the striking barrel 14 of the alarm mechanism which is the subject of this description is equipped with a stop.
  • the stops are devices which are known to those skilled in the art as such.
  • the stop serves on the one hand to limit the number of winding revolutions of the barrel during winding, and on the other hand it serves to prevent the mainspring from completely disarming.
  • FIG 2B is a schematic diagram of the operation of stopping the wake-up mechanism of this example.
  • the operating principle of the stop shown is similar to that of a traditional Maltese cross stop.
  • the illustrated stop has the particularity of being spread over two levels.
  • the two-level layout has the advantage of saving space in width.
  • FIG. 2B shows a portion of disc 81 and a finger 83 which are both fixed on the barrel shaft (not shown in the Figure 2B , but visible and referenced 79 in the Figure 2A ).
  • FIG. 2B also shows a partially toothed mobile 85 on two levels which is pivoted on a fixed shaft mounted on a bridge (not shown) near the barrel.
  • the first level of the mobile 85 is constituted by a partial star 87 which is arranged to cooperate with the finger 83
  • the second level is constituted by a cam 89 arranged to cooperate with the disc portion 81.
  • the cam 89 comprises a circular portion 91 and two concave portions 93a and 93b.
  • the direction in which it is necessary to rotate the shaft 79 to wind the barrel is the clockwise direction, and therefore conversely, the barrel is decocked by rotating the barrel shaft in the counterclockwise direction.
  • the angular position of the stopping mobile 85 in the Figures 2A and 2B corresponds to the situation where the mainspring 15 is fully armed.
  • the stop blocks the rotation of the barrel shaft in the clockwise direction by bracing the rectilinear side of the disc portion 81 against the cam 89 at the level of the end of the circular portion 91 which adjoins the concave portion 93a.
  • the barrel is however free to disarm by driving the shaft 79 in a counterclockwise direction.
  • the mainspring 15 disarms by driving the barrel shaft, it rotates the finger 83, so that the latter advances the star 87 by one step at each revolution.
  • the stopping mobile 85 has pivoted by 60°, the mainspring 15 having made the barrel shaft 79 complete two complete revolutions in disarming, the latter is blocked again due, this time, to the buttress of the rectilinear side of the disc portion 81 against the end of the circular portion 91 which adjoins the concave portion 93b. The stop thus prevents the barrel from disarming further.
  • the angular position of the stopping mobile 85 is a function of the degree of winding of the mainspring 15 and that, in the example illustrated, an angle of 60° separates the maximum winding position from the position minimum arming.
  • the alarm mechanism comprises a trigger system provided to control the triggering of the ringing mechanism at a programmed time, provided that the alarm mechanism is activated.
  • THE Figures 3A, 3B And 3C are schematic plan views of the trigger system of the alarm mechanism of the watch of the figure 1 .
  • the wake-up mechanism is in the “on” state, while it is in the “off” state in the Figure 3C , the trigger system then being locked.
  • the first of these three figures shows the system before the pre-programmed trigger time, and the second shows it just after the trigger.
  • the third figure shows the triggering system just after the programmed time, with the wake-up mechanism in the “off” state.
  • an alarm blocking lever 33 rotatably mounted on a pivot 34 and provided with a first arm arranged to cooperate with a toothed mobile 18 which is part of the small cog, a trigger cam 21 provided with a notch 23, and a trigger rocker 25 pivoted around an axis 27 and provided with a beak 29 which is returned against the cam 21 by a return spring 31.
  • the distal end of the rocker 25 carries a pin 32 arranged to cooperate with a second arm of the alarm locking lever 33.
  • the first arm of the lever 33 is inserted in the teeth of a four-pointed star 19 of the mobile 18.
  • Cam 21 is connected to the finishing train (not shown) of the watch so as to be driven to rotate counterclockwise (the cam being viewed from the angle shown in the figures). In accordance with the embodiment which is the subject of this example, the cam 21 completes one revolution in twenty-four hours.
  • the alarm mechanism also comprises an adjustment system, which may be of a known type, and which makes it possible to adjust the angular position of the cam 21 so that the notch 23 is located in face of the spout 29 at a programmed wake-up time.
  • the operating principle of the ringing mechanism trigger system is as follows. At the programmed wake-up time, the nozzle 29 suddenly falls into the notch 23, which causes the trigger rocker 25 to pivot around its axis 27 in a counterclockwise direction. Driven by the rocker, the pin 32 pivots the alarm locking lever 33 clockwise, which has the effect of releasing the mobile 18. The barrel is then free to rotate by driving the striking mechanism.
  • the Figures 3A, 3B And 3C also show a column wheel 41 and a control rocker 35.
  • the column wheel of the present example is double. It is more or less the back-to-back assembly of two column wheels of classic design.
  • the column wheel 41 essentially consists of a ratchet wheel 57, a first set of six teeth or columns 59 carried on the edge by the ratchet on the upper face of its board, and a second set of six teeth or columns 59A carried on edge by the ratchet on the underside of its board (only the first set of columns is visible in the Figures 3A, 3B And 3C ).
  • the columns have a cross section substantially in the shape of a truncated triangle.
  • the ratchet has 12 teeth (two teeth for each column of a set). It is in fact a two-stroke column wheel.
  • the wheel columns 41 When not activated, the wheel columns 41 is held in a stable angular position by a jump spring 58 whose end presses against the ratchet wheel.
  • the control rocker 35 for its part, is pivoted around an axis 37. It can also be seen that it is provided with a nose 39 and a pin 45.
  • the nose 39 is recalled against the columns 59 of the column wheel 41 by a return spring 43, and the pin 45 is arranged to cooperate with a foot 47 with which the trigger lever 25 is provided, so as to allow the trigger system to be locked or unlocked.
  • the control rocker 35 comprises a pin 45 which is arranged to cooperate with a foot 47 of the trigger rocker 25.
  • the pin 45 is kept away from the trajectory of the foot 47, and it cannot therefore hinder the pivoting of the trigger rocker 25 in one direction or the other. It will be understood that the trigger system is then unlocked.
  • the column wheel 41 is incremented by one step, the pivoting of the control rocker 35 in the counterclockwise direction is accompanied by a movement of the pin 45 towards the foot 47.
  • the wake-up mechanism of the present example also comprises an activation indicator member arranged to indicate whether the wake-up mechanism is in the “activated” state or in the “deactivated” state. ".
  • the activation indicator member is controlled by the control rocker 35 and, as already mentioned, it is arranged to appear in a window referenced 7 ( figure 1 ).
  • the alarm mechanism also comprises a striking winder comprising a rotary control rod and a disengageable kinematic connection which connects the control rod to the rotary input/output member of the barrel so as to allow the control rod to arm the mainspring of the barrel.
  • a striking winder comprising a rotary control rod and a disengageable kinematic connection which connects the control rod to the rotary input/output member of the barrel so as to allow the control rod to arm the mainspring of the barrel.
  • THE Figures 4A and 4B are partial schematic plan views of the alarm mechanism which is the subject of this example. These figures show more particularly the striking winder. It can be seen that the latter conventionally comprises a control rod (referenced 117) movable axially between a winding position and an alarm time correction position. It should be noted, however, that, according to a variant, the control rod could only be movable in rotation, without the possibility of sliding axially. Both of these arrangements are known to those skilled in the art, and they will not be
  • the winder of the present example also comprises a winding pinion 119, a crown mobile 121 arranged in the axis of the stem 117 so as to be driven by the latter, an intermediate ratchet return 127 arranged to be driven by the winding mobile crown, and a winding lever 125 arranged to pivot around an axis (not referenced).
  • the intermediate gear 127 is mounted loosely on the rocker 125 in an eccentric position, and the crown movable 121 is arranged concentrically with the pivot axis of the rocker 125.
  • This arrangement allows the intermediate ratchet gear 127 to mesh permanently with the crown wheel 121, so that the latter can kinematically connect the control rod 117 to the intermediate gear 127 independently of the pivoting of the rocker. This is the reason why the crown mobile 121 and the intermediate return 127 will also be called below the driving mobile and the driven mobile.
  • FIGS. 4A and 4B still show the rotary input/output mobile of the striking barrel 14, which is constituted by the toothed wheel 17 and the barrel shaft 79. It can also be seen that the toothed wheel 17 is engaged with a gear train formed by two references 129 and 131 which are intended to allow the barrel 14 to be wound.
  • the winding lever 125 is pivotally mounted around a axis (not referenced) which coincides with the axis of the crown mobile 121. The winder rocker is thus capable of evolving between a first extreme angular position illustrated in the Figure 4A and a second extreme angular position illustrated in the Figure 4B .
  • the operation of the disengageable kinematic connection which connects the control rod 117 to the rotary input/output member 79, 17 of the barrel is as follows.
  • the crown wheel 121 (or driving wheel) is driven in one direction or the other.
  • the driving mobile itself drives the intermediate return 127 (or driven mobile) in rotation.

  • the lever 139 also includes a second end which is arranged to cooperate with a finger 143 presented by the winding lever 125.
  • the wake-up mechanism comprises an automatic system arranged to deactivate it when the mainspring has disarmed up to a first predefined threshold value.
  • the stopping mobile 85 shown has four different levels. The two lower levels are, as we have seen, a star 87 and a cam 89 which together constitute the actual stopping mobile ( Fig. 2B ).
  • the third level of the mobile 85 is constituted by a first logical cam 61 which is rigidly fixed on the first two levels in a coaxial position.
  • the stopping mobile 85 also comprises a fourth level formed mainly by a second logic cam 95 which is pivotally mounted in a coaxial position above the first logic cam 61.
  • the board of the second logical cam is pierced with an oblong 97 which defines an arc of a circle concentric with the pivot axis of the cam.
  • the first logic cam 61 carries a pin 99 which is arranged to slide in the oblong 97.
  • the presence of this oblong allows the second logic cam 95 to pivot relative to the rest of the stopping mobile 85 at the interior of an angular sector whose extent is limited by the two ends of the oblong 97.
  • the Figure 2A also shows a latching lug 101 which is arranged in an opening of the first logical cam 61 so as to press against the lower face of the second logical cam 95 to maintain the latter frictionally in one of its two extreme angular positions.

  • the instantaneous trigger rocker is also provided with a caster 107 which is returned against the second logical cam 95 by a return spring 113.
  • the configuration shown in figure 5A corresponds to the situation where the barrel spring is fully loaded. It can be seen that in this configuration, the caster 107 rests against the constant radius profile portion 111 of the cam 95. Then, when the ringing mechanism is triggered and the barrel spring disarms, the stopping mobile 85 successively takes two steps of 30° in the clockwise direction. The second logical cam 95 remains integral in rotation with the rest of the stopping mobile 85 during the first 30° step. In fact, the pin 99 is then located at one end of the oblong 97, and it prevents the second logical cam 95 from pivoting relative to the rest of the stopping mobile 85 in the counterclockwise direction. Under these conditions, the caster 107 rolls against the profile portion 111.

  • the insulator 63 carries a pin 71 at its end farthest from the axis 65.
  • the insulator 63 is arranged, relative to to the column wheel 41, in such a way that the nose 69 rests against one of the columns 59A ( Figures 6A and 6B ) when the wake-up mechanism is in the activated state. And conversely, the nozzle 69 is located opposite the space between two columns 59A ( Figure 6C ) when the wake-up mechanism is in the disabled state.
  • the logic cam 61 is represented in an angular position such that the beak 67 of the insulator 63 rests against a portion of circular profile 61a of the cam.
  • the angular position of the logic cam 61 is representative of the degree of winding of the mainspring.
  • the logic cam is rotated so that the nose 67 of the insulator 63 is opposite the circular profile portion 61a, it is because the degree of winding of the mainspring is greater than the second predefined threshold value.
  • the second nozzle 69 of the insulator 63 rests against one of the six columns 59A of the column wheel 41.
  • the mainspring has at least partially disarmed by rotating the logic cam 61 counterclockwise. It can be understood that the degree of winding of the mainspring is now lower than the second predefined threshold value, since the nose 67 is no longer facing the circular profile portion 61a.
  • the nozzle 67 of the insulator 63 now faces another circular portion (referenced 61b) of profile of the cam 61, the radius of the circular profile portion 61b being significantly less than that of the circular profile portion 61a. It can be observed, however, that the nozzle 67 does not rest against the circular profile 61b, but on the contrary is suspended above the profile 61b. Indeed, the second nozzle 69 of the insulator 63 is always supported against the same column 59A of the column wheel 41, because the alarm mechanism is always activated, the ringing being in progress.
  • the nozzle 69 of the insulator 63 is lowered between two columns 59A of the column wheel 41. It will therefore be understood that the wake-up mechanism is now deactivated.
  • the insulator 63 carries a pin 71 at its end furthest from the axis 65. Still referring to the Figure 6C , we can see that the pin 71 is arranged to keep the pawl 55 of the manually operated mechanism away from the ratchet wheel 57 of the column wheel 41.
  • the wearer of the watch no longer has the possibility of incrementing the column wheel by actuating the push button 13. In the position illustrated, the insulator 63 in fact prevents the pawl 55 from engaging with the teeth of the the ratchet wheel 57.

  • the nose 67 of the insulator 63 rests against the circular profile portion 61a.
  • the first logical cam 61 which is integral with the arming mobile 85 ( Figure 2A and 2B ), is arranged to rotate counterclockwise when the barrel decocks. Under these conditions, when, following the triggering of the ringing, the first logic cam 61 begins to rotate, the nose 67 of the insulator 63 slides on the circular profile portion 61a up to the shoulder 62 separating this portion from profile of the profile portion 61b.
  • the nose 67 is located opposite the portion of circular profile 61b whose radius is significantly less than that of the circular profile 61a.
  • the other nozzle (the nozzle 69) of the insulator 63 rests against one of the columns 59A of the column wheel 41.
  • the insulator 63 does not tip when the spout 67 passes from the profile portion 61a to the profile portion 61b since it is still supported by its other beak which rests against one of the columns of the column wheel. It will be understood from the above that the isolator 63 does not interfere with the operation of the manually operated mechanism when the wake-up mechanism is in the activated state.
