Definitions

  • the present invention relates to a timepiece comprising a striking mechanism capable of operating at least in a repeater mode, in particular a minute repeater mode, in which it audibly indicates the current time on demand.
  • repeater mechanisms are powered either by a large striking barrel that the user winds up using a winding crown when the energy reserve is exhausted after several strikes, or by a small striking barrel that is wound up before each strike by means of a lock that the user manipulates to activate the repeater.
  • the repeater mechanism is only part of the striking mechanism, the latter also having, for example, a striking function in passing (so-called grande sonnerie or petite sonnerie mechanisms) or an alarm function (cf. CH 703635 ).
  • the striking barrel then constitutes the energy source for the entire striking mechanism.
  • the second case corresponds to striking mechanisms which only include a repeater function, as in the document EP3508925A1 , For example.
  • a large striking barrel wound by a winding crown requires in practice to provide a display of its energy reserve so that the user can know when to wind it, and the user must remember to check the energy level before activating the repeater.
  • the travel of the lock depends on the number of strokes to be struck so that the strike barrel is only recharged with the amount of energy necessary to sound the strike.
  • the lock stops in fact as soon as an hour feeler comes into contact with an hour snail to take the information of the number of hours to be struck, which, by moving an all or nothing, triggers the catch quarter and minute information by quarter and minute parts touching quarter and minute snails under the impulse of respective return springs.
  • the lock acts via a rack on the striking barrel shaft to wind the spring housed in the striking barrel drum.
  • the striking barrel shaft moves in the opposite direction under the action of the striking barrel spring and, regulated by a speed regulator, winds up an hour ratchet and the quarter and minute parts to strike the current hour.
  • the rack returns to its rest position at the rate imposed by the striking barrel shaft.
  • the striking barrel drum for its part, always remains fixed.
  • the force applied to the hour snail is that of the user. If the user exerts excessive force, this can cause breakage or cause the hour snail to turn until the hour feeler stops on the wrong step, giving false information on the number of strokes to strike.
  • the present invention aims to provide a repeating timepiece which remedies, at least in part, the aforementioned drawbacks.
  • a timepiece in particular a wristwatch, a pocket watch, a pendant watch or a small clock, comprising a striking mechanism capable of operating at least in a repeater mode, a striking barrel for powering the striking mechanism and a manual control member operable by the user to wind the striking barrel and activate the repeater mode, the striking barrel comprising a barrel drum, a barrel arbor and a spiral barrel spring housed in the barrel drum and coupled by its outer end to the barrel drum and by its inner end to the barrel arbor, the striking mechanism comprising at least one gong, at least one hammer for striking the at least one gong and an actuating device coupled to a first barrel element constituted by one of the barrel drum and the barrel shaft for actuating the at least one hammer, characterized in that a second barrel element constituted by the other of the barrel drum and the barrel shaft comprises a toothing with which a pawl cooperates, in that the manual control member is arranged to drive a control rack meshing, via a one-way clutch mobile
  • the present invention applies equally well to striking mechanisms having a repeater function combined with a second type of striking such as an alarm or a passing strike, as to striking mechanisms having only a repeater function.
  • the striking barrel can also be wound by a winding crown, the winding by said manual control member, typically a lock, then serving to preserve the power reserve of the second type of striking.
  • a timepiece which in the illustrated example is a wristwatch, comprises a case 2 containing a base movement, a striking mechanism connected to the base movement, a dial 8 and indicator hands or other indicator members associated with the dial 8.
  • the indicator hands typically comprise an hour indicator hand 10, a minute indicator hand 12 and a second indicator hand 14 actuated by the base movement, as well as an alarm hour hand 16.
  • the winding crown 18 can occupy three axial positions: a pushed position, an intermediate position and a pulled position.
  • a rotation of the winding crown 18 in the clockwise direction winds the basic movement.
  • a rotation of the winding crown 18 in the clockwise or counterclockwise direction makes it possible to set an alarm time.
  • a rotation of the winding crown 18 in the clockwise or counterclockwise direction makes it possible to set the current time (time of the basic movement).
  • the selection pusher 20 passes coaxially through the winding crown 18 and is axially movable relative thereto. The selection pusher 20 could nevertheless be separated from the winding crown 18.
  • the striking mechanism has a minute repeater operating mode and a alarm, the transition from one mode to the other being carried out by means of the selection pushbutton 20.
  • an actuation of the activation lock 22 i.e. a sliding of the activation lock 22 on the periphery of the case 2 between a rest position and an end-of-travel position, causes the striking mechanism to switch from a selected minute repeater state (block a) to an activated minute repeater state (block b) by triggering the striking of the hours, quarters and minutes of the current time.
  • the striking mechanism remains in the minute repeater mode until the selection pusher 20 is actuated.
  • actuation of the activation lock 22 causes the striking mechanism to transition from an alarm selected state (block c), where the striking mechanism is inactive, to an alarm activated state (block d), where the striking mechanism waits for the current time to reach a determined alarm time before triggering the striking of the hours, quarters and minutes of said alarm time (block e). Once the alarm time has been struck, the striking mechanism returns to its alarm selected state (block c).
  • minute repeater or alarm it is not possible to stop the chime once it has been triggered. The user must wait for the chime to end before being able to carry out a new operation on the timepiece.
  • the stroke of the activation lock 22 in the alarm mode is the same as in the minute repeater mode and does not depend on the number of strokes to be sounded, as will be explained later. Furthermore, both operating modes use the same energy source consisting of a striking barrel 24 (cf. figure 2 ) independent of the barrel of the base movement.
  • the base movement and the striking mechanism are mounted on a frame (not shown) classically formed of a plate and bridges.
  • the basic movement (not shown) is of the traditional type. It is located on the bridge side and includes a barrel acting as a power source, a gear train, an escapement and a sprung balance or other resonator.
  • the basic movement can be supplemented by an automatic winding mechanism designed to wind the barrel using the energy provided by the movements of the wearer of the timepiece.
  • the 24-hour strike barrel (cf. figures 4, 5, 6 And 10 ) consists of a barrel drum 52 housing a spiral barrel spring 54 and a toothing 56 secured to the barrel drum 52.
  • the barrel drum 52 is traversed, in a freely rotatable manner, by a barrel shaft 58 to which the inner end of the barrel spring 54 is attached, the outer end of the barrel spring 54 being coupled to the wall of the barrel drum 52 by a sliding flange 60, as will be explained later.
  • a fusee wheel 62 integral in rotation with the barrel arbor 58
  • a detent ratchet 64 free in rotation relative to the barrel arbor 58 and a spring 66 (visible in the figure). figure 27 ) prevents it from moving back, and a drive plate 68 integral in rotation with the barrel shaft 58.
  • the trigger ratchet 64 is held axially by two bearing screws 70 which pass through elongated holes 72 in the trigger ratchet 64 to be screwed into the drive plate 68.
  • the elongated holes 72 allow limited rotation of the trigger ratchet 64 relative to the drive plate 68.
  • the drive plate 68 carries a trigger pawl 74 and a return spring 76 for the trigger pawl.
  • a pin 78 carried by the trigger ratchet 64 passes through an opening 80 in the drive plate 68 large enough not to hinder the rotation of the latter. This pin 78 has the function of moving the trigger pawl 74 outwards, the end of which has an inclined surface 82 for this purpose.
  • the trigger pawl 74 is arranged to cooperate, by an engagement lug 84 which it comprises, with a barrel ratchet 86 free to rotate around a barrel 88 of the escapement plate 68.
  • an hour ratchet 90 Around the barrel of the barrel ratchet 86 are mounted an hour ratchet 90, a rack pinion on fusee 92, a quarter piece pinion 94 and a piece control finger quarters 96.
  • the hour ratchet 90, the rack pinion on fusee 92 and the quarter part control finger 96 are integral in rotation with the barrel ratchet 86.
  • the quarter part pinion 94 is, itself, free in rotation relative to the barrel ratchet 86 but is controlled by the quarter part control finger 96 by means of a pin 98 carried by the quarter part pinion 94.
  • the assembly 64, 68, 86, 90, 92, 94, 96 is held axially in one direction by a shoulder 100 of the barrel arbor 58 against which the drive plate 68 can bear and in the other direction by a nut 102 screwed onto one end of the barrel arbor 58.
  • the assembly 64, 68, 86, 90, 92, 94, 96 is located on the dial side while the striking barrel 24 and the fusee wheel 62 are located on the bridge side.
  • the assembly 64, 68, 86, 90, 92, 94, 96 constitutes a trigger fuse of the type found in grand strike mechanisms where the strike can be triggered manually (on demand) or automatically (on the fly). It makes it possible to decouple the strike barrel 24 from the parts used to actuate the hammers 40, 42 to allow the collection of information on the number of strokes to be struck and to couple the strike barrel 24 to said parts used to actuate the hammers 40, 42 after the collection of information to sound the strike.
  • the barrel drum 52 by its teeth 56, meshes with the wheel 104 of a one-way clutch mobile 106 (cf. Figures 7 and 8 ).
  • the pinion 108 of the one-way clutch mobile 106 coupled to the wheel 104 by a ratchet disengageable system, is engaged with a toothed sector 110 of a control rack 112 actuated by the activation lock 22.
  • the control rack 112 pivots about a point 114 and has a slot 116 in which a fixed pin 118 is engaged (visible in FIG. figure 27 ) acting as a stop defining two limit positions of the control rack 112, namely a rest position and an end-of-travel position.
  • a rack return spring 120 acts on the control rack 112 for the maintain in its rest position when not actuated by the activation lock 22.
  • the control rack 112 serves to wind the barrel spring 54 via the barrel drum 52.
  • a pawl 122 engaged in the teeth 56 under the action of a pawl return spring 123 prevents the striking barrel 24 from unwinding via the barrel drum 52.
  • the control rack 112 further serves to actuate a winding pawl 124 positioned by a winding pawl spring 126 - the winding pawl 124 and the winding pawl spring 126 are visible at figure 27 - to set the trigger ratchet 64 in motion and thus disengage the trigger pawl 74, more precisely its engagement lug 84, from the teeth of the barrel ratchet 86 by means of the pin 78 carried by the trigger ratchet 64.
  • the wheel 104 and the pinion 108 of the one-way clutch mobile 106 are integral in rotation in one direction and free in rotation relative to each other in the other direction.
  • the movement of the control rack 112 by the activation lock 22 causes the pinion 108 to rotate in the direction in which it is secured to the wheel 104.
  • the wheel 104 driven by the pinion 108 in turn drives the barrel drum 52, which arms the barrel spring 54.
  • each actuation of the activation lock 22 winds the striking barrel 24.
  • control rack 112 is released by the action of its spring 120 and returns to its rest position by rotating the pinion 108 but not the wheel 104 which, in this direction, is disengaged from the pinion 108 and retained by the teeth 56 itself retained by the pawl 122.
  • the control rack 112 For its drive by the activation lock 22, the control rack 112 comprises an arm 128 that a pin (not shown) carried by the activation lock 22 can push against the action of the rack return spring 120 and against the action of a return spring of the activation lock 22.
  • the activation lock 22 is movable between a rest position where its return spring presses it against a stop of the box 2 and an end position of travel where it is supported against the control rack 112 itself at the end of travel against the pin 118 (cf. figure 28 ).
  • the one-way clutch mobile 106 (cf. figure 9 ) is for example as described in international patent application no. PCT/IB2020/060506 of the applicant.
  • the wheel 104 comprises an internal toothing 132 with asymmetrical teeth which delimits a housing 134 in which there are a rigid pawl 136, a rigid drive member 138 and an elastic blade 140 connecting the rigid pawl 136 to the rigid drive member 138.
  • the rigid drive member 138 is integral in rotation with the pinion 108.
  • the wheel 104 is mounted loosely around the axis 142 of the pinion 108 and is made integral with the pinion 108 in one direction of rotation by the rigid pawl 136 blocked by the rigid drive member 138 against a tooth of the internal toothing 132. In the other direction of rotation, the rigid pawl 136 unlatches and thus separates the wheel 104 from the pinion 108.
  • the striking barrel 24 has a sliding flange 60. It is therefore a barrel which resembles that of self-winding watches, the sliding flange 60 serving to avoid any overtension in the barrel spring 54. Indeed, unlike conventional minute repeater mechanisms where the degree of winding of the striking barrel depends on the number of strokes to be struck, the striking barrel 24 in the present invention is fully wound each time the activation lock 22 is actuation, this in order to guarantee sufficient energy for the maximum number of strokes that the striking mechanism 6 may have to sound depending on the alarm time that the user has programmed.
  • This 60 sliding flange is shown in the figure 10 . It may comprise protrusions 144 cooperating with corresponding notches provided in the wall of the barrel drum 52 to index positions of the sliding flange 60 along said wall between which the sliding flange 60 can slide in the event of overtension of the barrel spring 54.
  • the fusee wheel 62 is kinematically connected to the speed regulator 48 via the striking gear train 50, also called the "small gear train", which is a multiplier gear train.
  • the speed regulator 48 makes it possible to regulate the rotation speed of the striking gear train 50 and the barrel arbor 58.
  • a propeller 146 for locking and unlocking the striking gear train 50 is coaxial and integral with the speed regulator 48.
  • the output torque of the striking gear train 50 is very low, such that a simple tangent contact on the propeller 146 is sufficient to stop the entire striking gear train 50 and the barrel arbor 58. This tangent contact is ensured by a propeller stop lever 148 when the latter is constrained by a quarter part 150 as shown in figure 11 .
  • the quarter piece 150 includes on its periphery two series 152, 154 of three teeth.
  • the first series 152 is intended to cause a first lifting of the quarters (not shown) raising a small hammer 42 striking a high-pitched gong 46 (cf. figures 11 And 3 ), and the second series 154 is intended to drive a second quarter lift (not shown) raising a large hammer 40 striking a low-pitched gong 44.
  • the quarter piece 150 further has an internal toothing 156 engaging with the quarter piece pinion 94.
  • the quarter piece quarters 150 also has a quarter feeler 158. This quarter feeler 158 is arranged to rest on the steps of a quarter snail 160 (cf.
  • the quarter snail 160 is coaxial with the cannon pinion of the base movement. In addition, it carries a pin 164 which, with each turn of the cannon pinion, advances by one tooth a twelve-pointed star 166 carrying an hour snail 168.
  • the barrel ratchet 86 In the rest state of the striking mechanism 6 ( minute repeater selected or alarm selected state), the barrel ratchet 86 is secured to the barrel arbor 58 by the cooperation between the trigger pawl 74 and the barrel ratchet 86, and the quarter piece 150 subjected to the action of the barrel arbor 58 via the barrel ratchet 86, the quarter piece control finger 96 and the quarter piece pinion 94 is blocked by the helix 146 in a high position, away from the quarter snail 160, against the force of the quarter piece return spring 162.
  • a snail of minutes 170 (cf. figure 14 ) is coaxial and integral with the cannon-pinion. On the steps of this minute snail 170 can be supported a minute feeler 172 of a minute piece 174 to determine the number of minutes to be struck.
  • the minute piece 174 is mounted on the same axis 176 as the quarter piece 150 and is subjected to the action of a minute piece return spring 178.
  • the minute piece 174 is provided with a first toothed sector 180 of fourteen teeth intended to cause a lift of the minutes raising the small hammer 42.
  • the minute piece 174 has a second toothed sector 182 which cooperates in a traditional manner with a minute hook 184 carried by the quarter piece 150.
  • the hour ratchet 90 is intended to drive a lift of the hours raising the large hammer 40.
  • the rack pinion on spindle 92 integral with the hour ratchet 90, meshes with the toothed sector 186 of a rack or hour rack 188 (cf. Figures 4 to 6 And 12 ) subjected to the action of a return spring of the hour rack 190 and which includes an hour feeler 192 capable of coming to bear on the steps of the hour snail 168 to determine the number of hours to be struck.
  • a pin 194 carried by the quarter piece 150 serves to retain the hour rack 188 for a certain time during the fall of the quarter piece 150 towards the quarter snail 160.
  • the quarter snail 160 and the minute snail 170 is freely mounted a surprise 196.
  • a pin 198 (cf. figures 12 And 14 ) implanted in the minute snail 170 and engaged in a larger hole 200 in the surprise 196 limits the rotational mobility of the surprise 196 relative to the minute snail 170.
  • the quarter snail 160 is integral with the surprise 196 and defines a spring 202 which acts on the pin 198. This spring 202 tends to angularly align the surprise 196 with the minute snail 170.
  • a surprise has the function of extending the 0 step of each branch of the minute snail when no minute is to be struck, in order to prevent the minute feeler from inadvertently falling on the fourteenth step of the adjacent branch.
  • Surprise 196 is activated before each strike, when the hour to be struck is an hour without a minute to be struck or an hour that slightly precedes (typically by one or two minutes) an hour without a minute to be struck, by a quarter jumper 204 which angularly offsets it relative to the minute snail 170 against the action of spring 202. After the strike, surprise 196 returns to its rest position.
  • the activation of the surprise 196 does not occur when the activation lock 22 is actuated, as in a conventional minute repeater, but during the fall of the quarter pieces 150 and minutes 174 and the hour rack 188 onto their snails 160, 170, 168, more precisely during the fall of the hour rack 188.
  • the quarter jumper 204 is controlled by the hour rack 188 via a pin 206 carried by the hour rack 188 and against which an arm of the quarter jumper 204 rests under the action of a quarter jumper return spring 208. Each time the hour rack 188 falls towards the hour snail 168, it authorizes the quarter jumper 204 to approach surprise 196.
  • This movement of the quarter jumper 204 has most of the time no effect on surprise 196 given the angular position of the latter, but when the hour to be struck is an hour without a minute to be struck or an hour which slightly precedes an hour without a minute to be struck, the quarter jumper 204 comes into contact with surprise 196 to offset it angularly relative to the minute snail 170.
  • the quarter jumper 204 is only in the path of the surprise 196 during the strike triggering phase and does not need to be lifted every quarter hour by the surprise 196 between the time when the alarm is activated by actuation of the activation lock 22 and the time when the current time coincides with the determined alarm time. Energy consumption is thus reduced.
  • minute piece 174 may be very close to minute snail 170.
  • the time it takes for minute piece 174 to fall until it reaches minute snail 170 may be too short to allow hour rack 188 to activate surprise 196.
  • the mechanism of chime 6 is provided with a minute blocker 210 arranged to delay the fall of the minute piece 174 until the surprise 196 is activated by the hour rack 188.
  • the 210 minute blocker is particularly visible at the figure 14 . It pivots around a point 212 and its rest position is defined by a pin 214 against which it rests under the action of a return spring 216.
  • a first arm 218 of the minute blocker 210 serves as a stop for a pin 220 carried by the minute piece 174 to stop the minute piece 174 when the quarter piece 150, the minute piece 174 and the hour rack 188 fall.
  • a second arm 222 of the minute blocker 210 is struck by the pin 206 of the hour rack 188 after the hour rack 188 has allowed the quarter jumper 204 to move towards the surprise 196 to activate it or not depending on the hour to be struck. This cooperation between the hour rack 188 and the minute blocker 210 lifts the minute blocker 210 and releases the minute piece 174 which can thus fall onto the minute snail 170 to take the information of the number of minutes to strike.
  • the striking mechanism 6 includes (cf. figures 15 to 20 ) a column wheel 224 consisting of a ratchet 226, a column stage 228 and a cap 230, these three elements 226, 228, 230 being mounted integrally around a column wheel axle 232.
  • the column wheel 224 is positioned by a jumper 234 cooperating with the ratchet 226. It is controlled by the selection pusher 20 via, successively, an intermediate lever 236, a control 238 and a control hook 240 (more visible in the figure) figure 36 ) engaged in the teeth of the ratchet 226.
  • the ratchet 226 has twelve teeth and the column stage 228 has six columns.
  • the active faces RM of the columns of the column stage 228 correspond to the minute repeater mode while the gaps AL between two columns correspond to the alarm mode.
  • the cap 230 is located in the example illustrated between the ratchet 226 and the column stage 228. It has in its lower face, that is to say the face furthest from the column stage 228, a hollow 242 which surrounds the column wheel axle 232.
  • the two walls which laterally delimit the hollow 242 constitute star-shaped cams for the inner wall 244 and of generally polygonal shape for the outer wall 246.
  • the vertices RM of the star and the polygon are angularly aligned with the active faces RM of the columns and also correspond to the minute repeater mode.
  • the zones AL of the hollow 242 between the vertices RM correspond to the alarm mode.
  • the principle of the operating mode selection is to allow the quarter piece 150 to fall immediately after the activation lock 22 is actuated when the striking mechanism 6 is in the minute repeater mode, to trigger the striking of the hours, quarters and minutes of the current time, and to prevent the quarter piece 150 from falling beyond an intermediate waiting position, until the current time corresponds to the determined alarm time, when the striking mechanism 6 is in the alarm mode.
  • the support of the second inclined surface 262 of the alarm triggering lever jumper 256 on the first pin 252 keeps the latter in the rotation path of the stop 264 of the quarter piece 150 and therefore prevents the quarter piece 150 from falling onto the quarter snail 160 and triggering the strike.
  • the quarter piece 150 stops on the first pin 252, which corresponds to the intermediate waiting position mentioned higher. In this position, the second pin 254 is not in contact with either of the two walls 244, 246 of the recess 242 and the secondary alarm triggering rocker 248 is retained by the primary alarm triggering rocker 268 which, here, is in contact with the output cam 270 of the alarm differential 272.
  • the secondary alarm triggering lever 248 is provided with a tab 274.
  • the secondary alarm triggering lever 248 further comprises a finger 276 capable of cooperating with a cannon pinion nut 278, coaxial and integral with the cannon pinion of the base movement, having four notches 280 (cf. figure 21 ) representative of the quarters to be sounded in alarm mode.
  • the primary alarm triggering rocker 268 comprises on its periphery two legs 282, 284 capable of interacting with the leg 274 of the secondary alarm triggering rocker 248 and an arm 286 passing under the output cam 270 of the alarm differential 272 and the end of which is surmounted by a lug 288 arranged to cooperate with this output cam 270.
  • the primary alarm triggering rocker 268 is pivoted not around a physical axis but around a virtual axis by means of a flexible guide 290 suspending it from a fixed base 292.
  • the alarm differential 272 is used to compare the current time with the determined alarm time.
  • Two diametrically opposed notches 294 in the output cam 270 define two angular positions of the output cam 270 (one per twelve hours) in which the current time coincides with the determined alarm time.
