Definitions

  • the present invention relates to a mechanical timepiece or electromechanical system comprising in particular an alarm mechanism capable of trigger an alarm at a specified alarm time.
  • the document CH 644 984 proposes for example an alarm mechanism comprising first and second mobiles and a plate detector mounted on the same tree.
  • the first and second mobiles are respectively engaged with the hour wheel and an alarm wheel and are all two with housing.
  • Each of these units has, on one side, a ramp and, on the other, a substantially vertical flank.
  • Prominent bosses are arranged on the detector plate, these bosses having a ramp on one side and a substantially vertical flank of the other.
  • This conductive plate is also constrained by a spring towards the first and second mobiles.
  • the first mobile is constantly pushing the detector plate during its normal rotation and the makes it turn.
  • a general object of the present invention is therefore to propose a part watchmaking system enabling the execution of time-setting and / or change of spindle in both directions while avoiding the triggering of the waking mechanism during these operations.
  • Another object of the present invention is to limit the effect of brake caused by the presence of the waking mechanism.
  • the disengaging device comprises a disengaging lever actuated by the correcting rod (preferably by via a zipper), the corrective rod being able to occupy a first position in which the disengaging lever does not interfere with the operation of the awakening mechanism and at least a second position, called correction, in which one end of the disengaging lever blocks the axial displacement of the first mobile.
  • the timepiece may further include a mechanism for change of time zone to allow a correction operation of the indication of the hour by whole step of one hour.
  • the disengaging device is in further arranged to prevent the axial displacement of the first mobile during this other correction operation.
  • a part watchmaking timepiece comprising an alarm mechanism indexed to that of the time zone.
  • electronic watches allow a moment of relative alarm either at the reference time, that is, the time of where the person usually resides, that is, the local time, that is, the time where the person is momentarily during their travels.
  • the mechanical or electromechanical watches with known time zone equipped in addition to an alarm mechanism, they only allowed the to set the alarm time relative to the reference time, where then obliged that person to engage in calculations always tedious and often source of error if she wanted the wake-up time to be in line with the time zone of the place where she was staying temporarily.
  • the waking mechanism is advantageously automatically adjust according to the time zone of the location where the person, so that the person will be alerted at the same time regarding local time.
  • the embodiment presented hereinafter is a timepiece of the type wristwatch. It goes without saying that this example is given for illustrative purposes only only and that the invention can be applied to any type of timepiece.
  • the present invention applies to a watch of the type mechanical or electromechanical, that is to say a watch comprising a movement mechanically driven by a barrel or by a battery that can be recharged after exhausted or replaced.
  • FIG. 1 is a plan view, on the dial side, of a wristwatch according to the invention. Designated as a whole by the general numerical reference 1, the dial features classically hour 2 indexes. Above the dial 1 stands move an hour hand 4, a minute hand 6 and a needle seconds 8.
  • the watch also comprises an alarm clock 10 which, by its position vis-à-vis the hour 2 indexes, indicates when the waking mechanism will take office. It can be seen here that the wake-up time is indicated by a single needle. It goes without saying that the waking mechanism and the associated means alarm time could be changed to allow adjustment and a more accurate display of the alarm time. On the other hand, it will be understood that the needle or the wakeup hands may be off-center to allow a display of the waking time in an additional dial.
  • a symbol 14 which indicates whether the alarm clock mechanism is activated or deactivated, i.e. if a tone will sound at the specified alarm time.
  • a second window optional 16 appears the date of the day or date.
  • an extra needle 18 moves over a second dial 20.
  • This needle 18 indicates in the reference time, that is the time that the person almost always on his watch, and that corresponds to the time zone of the place where this person has his home or business premises.
  • the set of needles 4, 6, 8 indicates the local time, that is the time in the time zone where the person is momentarily during a trip.
  • the needle 18 which indicates the reference time and the hour hand 4 which indicates the time zone of the place where the person is momentarily spindle needle provide the same hourly indication.
  • the position of the needle of spindle 4 is changed by the user to coincide the indication provided by said spindle needle 4 with the local time of the place where that person is momentarily, so that the reference needle 18 and the spindle needle 4 provide different indications.
  • the wristwatch of FIG. 1 further comprises two crown rods A and B. These rods can also serve as a winding.
  • the first stem-crown A is used in particular to allow the setting of the time local and reference time, in particular.
  • the second crown rod B is used to allow setting the wake time.
  • the wristwatch of Figure 1 finally has a push-button C controlling an activation mechanism and deactivation of the alarm clock. In response to pressing this push button C, the user can activate or deactivate the striking mechanism the alarm, the activation or deactivation state being indicated, as mentioned above, by the symbol 14 in the window 12.
  • FIG. 2 is a sectional view of the time zone mechanisms and awakening.
  • a driving floor 22 controlling the timer and which is driven by the movement at the rate of one turn in one hour.
  • This 22 is rotatably mounted around a center post 43 itself crossed by the axis 44 of the mobile seconds.
  • the driving floor 22 meshes with a mobile timer 24 which includes a timer wheel 26 on the axis of which is chased a pinion timer 28.
  • a pinion timer twenty-four hours 30 is rotatably mounted between the timer wheel 26 and the timer gear 28. It is possible, by acting on the timer gear 30, to change the indication of time zone via a spindle wheel 32 as will be seen in detail later.
  • the timer pinion 28 rotates the hour wheel 34 which is mounted free to rotate around the needle barrel of 40 hours and which, for its axial retention, based on a shoulder 58 that presents this same gun 40.
  • the rotational movement of the hour wheel 34 is transmitted at the hour handgun 40 via the jumper 36 which is secured to said wheel of 34 hours via a nipple 60 hunted in a shape opening 62 corresponding in said hour wheel 34.
  • This jumper 36 is engaged with the star with twelve teeth 38 itself secured to the needle gun hours 40.
  • the hours needle gun 40 rotates simultaneously the hour hand, also called the spindle needle 4.
  • the timer gear 28 meshes with the gear train (not shown) of the reference time shown by the additional needle 18.
  • the additional needle or reference needle 18 and the spindle needle 4 provide the same hourly indication, which means that the no one is at his usual place of residence where he is domiciled or commercial buildings.
  • the 40-hour wheel cannon leads to rotation the interlocking core 50 of the waking mechanism via the coach 56.
  • the engagement core 50 slides by its bosses 52 on the wheel trigger 46 until the time provided by the spindle needle 4 coincides with the wake up time.
  • the bosses 52 of the interlocking core 50 dive into the housing 54 of the trigger wheel 46, causing the triggering the alarm mechanism.
  • the coach 56 integral with the 40-hour needle gun, also turns and drives the core interlocking 50 of the alarm mechanism.
  • the engagement core 50 slides through its bosses 52 on the trigger wheel 46 and performs an angular displacement identical to that of the needle barrel 40 hours, so the wake up time that was initially set relative to the reference time remains the same relative to the new time zone displayed after the correction. So, thanks to this feature, the wake up time is corrected concordantly and at the same time correcting the spindle time schedule. It should be noted that during the spindle time correction phase time, the waking needle 10 remains motionless.
  • the output of the housing bosses 52 54 is facilitated by the fact that these bosses 52 have inclined planes 68 (see Figure 3b).
  • the trigger wheel 46 is pressed against a mechanism cover 70 and is virtually motionless except when operated from the outside of the watch to correct the position of the waking needle 10.
  • the 40-hour needle gun drives the core of engagement 50 in a concomitant movement and bosses 52 of this core 50 progressively exit housing 54 practiced in the wheel of trigger 46 sliding by their inclined planes 68 on the outline of these 54.
  • the interlocking core 50 has three openings 72 in which are housed three corresponding arms 57 (cf. Figure 5c) of the coach 56 for the rotational coupling of these two parts.
  • Figure 4 is a plan view of the spindle change mechanism.
  • the spindle wheel 32 is not illustrated to discover the jumper 36 and the star with twelve teeth 38.
  • the jumper 36 comprises a flat part stamped in 60 to form a nipple that fits into the shape opening 62 corresponding in the hour wheel 34.
  • the jumper 36 presents substantially the shape of a U with two elastic arms 76 stamped at 78 for forming two nipples able to slide each in an oblong hole 80.
  • Each of two elastic arms 76 of the jumper 36 ends with a head 82 provided with a spout 84 which is housed in a hollow between two successive teeth 64 of the star at twelve 38.
  • the oblong holes 80 can guide the arms 76 of the jumper 38 and impose on them a precise positioning.
  • the noses 84 of the heads 82 of the jumper 38 deviate from their rest position in a hollow between two teeth 64 of said star 38 and fall into the immediately following hollow under the effect of their elasticity.
  • the jumper 36 thus makes it possible to index the position of the star 38, so that, when changing timezone, the hours needle gun 40 advance by successive jumps of a twelfth of a turn each time. The correction of the time of time is thus made by changing from one hour to the next without that the timer mechanism is affected by this change.
  • the anchoring points of the jumper 36 were formed by nipples 60 and 78 stamped. With this feature, the jumper 36 can be made in one piece and has a small footprint. Of course, according to a variant, the nipples could be replaced by pins. The jumper 36 is maintained axially between the plates of the spindle wheel 32 and the hour wheel 34 ( Figure 2).
  • the waking mechanism can also contribute to slowing down the rotation of the 40 hours needle gun, due in particular to the friction between the core latch 50 and the trigger wheel 46 and the potential interaction of the bosses 52 and dwellings 54.
  • This brake may be a problem in the as it interferes with the smooth functioning of the change mechanism of spindle described above.
  • a device is proposed to disengage the waking mechanism when the user undertakes a setting the time of the watch or a change of time.
  • This disengagement device will now be presented with reference to Figures 5a, 5b, 5c, 6a, 6b, 7a and 7b.
  • the hammer spring 100 advantageously forms, in this example, also a trigger lever of the alarm mechanism.
  • the element 100 thus fulfills two functions. Therefore, in the remainder of this description, the terms "hammer spring” or “trigger lever” will be used to qualify the same element 100. It goes without saying that two separate parts could be used to separately perform the functions of the hammer spring and the lever of trigger.
  • the trigger lever 100 is terminated at one of its ends by a spout 102 which cooperates with a hammer pin 122, itself secured to a hammer 120 that can be actuated by its mechanism of training, not shown, to hit a stamp 125 shown schematically in the figure.
  • the trip lever 100 follows the movement of the engagement core 50 and the spout 102 releases the hammer pin 122 allowing the drive of the hammer 120.
  • the opposite end 104 of the trip lever / hammer spring 100 becomes typically ends in "T". It is this part, made integral with a platinum or a bridge, which actually forms the hammer spring for exercising a axial force on the engagement core 50 of the alarm mechanism.
  • the trigger lever 100 is secured in translation of the core latch 50, i.e. it is fitted to the interlocking core 50 and follows any axial displacement of the engagement core 50.
  • the core interlocking 50 can nevertheless be rotated without driving with him the trigger lever 100.
  • Figure 5c illustrates in more detail the connection between the trigger lever 100 and the interlocking core.
  • a throat 51 is thus arranged at the base of the interlocking core 50 (see also Figure 3b) for allow the axial retention of the trip lever 100.
  • the middle part, designated 105, the trip lever 100 is advantageously provided with a port 106 having walls 107, 108 which enclose the engagement core 50 by its groove 51.
  • the orifice 106 has an opening according to the external profile of an "8", that is to say two circular openings eccentric and of different diameter. Most wide of these openings is designated by the numeral 106a, the lowest by the reference numeral 106b.
  • the diameter of the opening 106a is chosen higher at the outer diameter of the base of the interlocking core 50 while the diameter the opening 106b is chosen slightly larger than the diameter of the groove 51.
  • FIG. 5c one can also see the three arms 57 of the coach 56, itself integral with the barrel of the hour hand 40, which allow the training in rotation of the engagement core 50 through the openings 72 already mentioned.
  • the disengaging mechanism of the mechanism is actuated by the stem-crown A.
  • this disengaging device is arranged to prevent axial displacement of the interlocking core 50 during a correction operation of the time indication local.
  • the disengagement device 200 comprises in particular a release lever 210 which is actuated by the crown rod A. The latter can occupy a first position (position illustrated in FIGS. 5a and 5b) in which the lever of declutching 210 does not interfere with the operation of the wakeup mechanism.
  • the stem-crown A can occupy at least a second position, called correction, in which one end 212 of the release lever 210 comes to block the displacement axial axis of the engagement core 50.
  • the rod A can thus occupying a first correction position (first drawn position - figures 6a and 6b) in which the user can, in particular, operate a time zone change by through the aforementioned mechanism and a second correction position (second position drawn - FIGS. 7a and 7b) in which the user can operate classic way a time setting of the watch.
  • the rod A activates, in a conventional manner, a zipper 202 which in turn actuates the release lever 210.
  • the clutch lever 210 takes the form of a fork comprising an elongated base 215 terminated by a pair of arms 216, 217 of which at least one (here the arm 216) is intended to prevent axial displacement of the interlocking core 50.
  • the release lever 210 is rotatably mounted on the zipper 202, by its extended base 215, by means of a pin 205.
  • the disengagement device further comprises guide means 220 constraining the lever of declutch 210 to move substantially in translation under the action of the zipper 202. More particularly, these guiding means 220 comprise a pin fixed 225 enclosed by the pair of arms 216, 217 of the release lever 210, the space separating the two arms 216, 217 acting in the manner of a guide rail.
  • the disengaging device 200 is intended to interact with the interlocking core 50 not directly but by via the trigger lever 100. Direct interaction with the core interlocking 50 is however perfectly conceivable.
  • the advantage of illustrated solution lies in the fact that one avoids in this way that the end 212 of the disengaging lever 210 rubs against a mobile rotated during the correction operations, namely the interlocking core 50 in this case.
  • FIGS. 6a, 6b, 7a and 7b the end 212 of the lever declutch 210 (and in particular the end of the arm 216) moves in the direction trigger lever 100, under the action of the rod A and the zipper 202, to come take support against this trigger lever 100 on the side where it is likely to move (here on the side of the dial 1).
  • the end 212 of the release lever 210 comes to prevent any axial displacement of the trigger lever 100, thus preventing any axial displacement of the engagement core 50 to the other mobile mechanism of awakening, namely the trigger wheel 46.
  • FIGS. 6a, 6b, on the one hand, and FIGS. 7a, 7b, on the other hand essentially reside in the more advanced position, in FIGS. 7a, 7b, of the clutch release lever 210.
  • the end of the release lever 210 which is intended to cooperate with the waking mechanism namely in particular the end of the arm 216, is preferably bent in the interlocking direction of the core 50 (here towards the dial) to ensure, if necessary, that the interlocking core 50 is brought into its non-engaged (or disengaged) position, even if this core had moved in the direction of the trigger wheel 46 (that is, in the eventuality when the correction operation is performed while the time of the spindle coincides with the waking time).
  • the end of the arm 217 is also preferably curved in this way to avoid any risk of collision with the lever 100, in particular in the correction position illustrated in FIGS. Figures 7a and 7b.
  • the device for disengagement could alternately act directly on the engagement core 50 rather than through the trigger lever 100.
  • the bottom line lies in the fact that the axial displacement of the interlocking core 50 is prevented during correction operations.
  • the wakeup mechanism requires generally two mobile superimposed and rotatably mounted around the same axis, one of the mobiles being able to undergo an axial displacement in the direction of the other when the time indication coincides with the alarm time. He is not necessary that the mobile which undergoes the axial displacement is the mobile driven by the mobile hours as in the example proposed. It is perfectly possible whether the other mobile (or mobile alarm) that undergoes axial displacement, in which case the disengagement device must interact with this other mobile.
  • the terms "first mobile” have been used to designate the mobile of the awakening mechanism that undergoes axial displacement
  • second “mobile” designate the other mobile of the alarm mechanism which does not undergo axial displacement.
