Definitions

  • the present invention relates to a timepiece comprising a striking mechanism combining a repeater mechanism, audibly indicating the current time on demand, and an alarm or wake-up mechanism.
  • Such a timepiece is described in the patent CH 703635 of the present applicant.
  • the alarm mechanism it comprises uses the quarter and minute parts and the hour rack of the repeater mechanism to strike the alarm time, but retains them before they come into contact with their respective snails until the current time coincides with the alarm time programmed by the user.
  • First and second pushers on the case of the timepiece allow the user to activate the repeater mechanism, to strike the current time, and the alarm mechanism respectively.
  • the alarm mechanism When the alarm mechanism is activated, the repeater mechanism cannot be triggered.
  • a display device indicates the state, activated or deactivated, of the alarm mechanism.
  • This timepiece according to the patent CH 703635 has the disadvantage of requiring, as a source of energy for the repeater and alarm mechanisms, a striking barrel wound by a winding crown.
  • This barrel must be able to store a large quantity of energy, and therefore be large, to avoid the user having to wind it often.
  • it requires providing 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 or the alarm.
  • Other timepieces operating in this way are known, as the document further discloses CH703615A2 , For example.
  • the present invention aims to provide a repeater and alarm timepiece which remedies, at least in part, the aforementioned drawbacks and which is simple to use.
  • a timepiece in particular a wristwatch, a pocket watch, a pendant watch or a clock, comprising a striking mechanism capable of operating in a repeater mode or an alarm mode, a mechanical energy source for powering the striking mechanism and manual control members for controlling the striking mechanism, the striking mechanism being arranged to produce an audible indication of the current time when the repeater mode is activated and to produce at a determined alarm time an audible indication of said alarm time when the alarm mode is activated, characterized in that the manual control members comprise a first manual control member for selecting one or other of the repeater and alarm modes and a second manual control member for arming the mechanical energy source and activating the selected mode.
  • the power source Since the power source is armed before each strike, it can be small, like the barrels of traditional non-alarm repeater mechanisms.
  • the arming of the power source is transparent to the user, since the same control member, preferably a lock, allows this arming and the activation of the repeat or alarm mode. It should also be noted that activating the repeat mode and the alarm mode using the same control member provides ease of use.
  • 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 allows an alarm time to be set.
  • a rotation of the winding crown 18 in the clockwise or counterclockwise direction allows the current time (basic movement time) to be set.
  • 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, switching from one mode to the other being carried out using the selection button 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).
  • Said determined alarm time may be a user-programmed alarm time, indicated by the alarm hour hand 16, or an alarm time dependent on a user-programmed alarm time.
  • the alarm time can only be set by the user in fifteen-minute steps over twelve hours, either at the full hour, the hour and a quarter, the hour and a half or the hour and three-quarters, and said determined alarm time at which the bell is triggered is the user-programmed alarm time less one or two minutes, in order to increase the number of strikes to be sounded and make the time indication particularly audible to the user.
  • the striking mechanism When the striking mechanism is in the alarm activated state (block d) and the striking has not yet been triggered, the user can, by pressing the selection pusher 20, return to minute repeater mode where he can at any time strike the current time by activating the activation lock 22.
  • 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 perform any further 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 (see Figure 2 ) independent of the barrel of the base movement.
  • the basic 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 going train, an escapement and a sprung balance or other resonator.
  • the basic movement can be supplemented by a self-winding mechanism designed to wind the barrel using the energy provided by the movements of the wearer of the timepiece.
  • the striking mechanism designated 6 in the drawings, is located partly on the bridge side and partly on the dial side, but mainly on the dial side.
  • On the bridge side ( Figure 2 ), there are hammers 40, 42 and gongs 44, 46, as well as the striking barrel 24, a speed regulator 48, for example of the flywheel type, and a striking train 50 connecting the striking barrel 24 to the speed regulator 48.
  • the rest of the striking mechanism 6 (cf. Figure 12 ) is located on the dial side.
  • 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, freely rotatable, 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.
  • 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 for this purpose an inclined surface 82.
  • 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, a rack pinion on fusee 92, a quarter piece pinion 94 and a piece control finger of the quarters 96 are mounted around the barrel of the barrel ratchet 86.
  • the hour ratchet 90, the rack pinion on fusee 92 and the quarter part control finger 96 are integral in rotation with the cannon ratchet 86.
  • the quarter part pinion 94 is, itself, free in rotation relative to the cannon 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 way). It makes it possible to decouple the striking barrel 24 from the parts used to actuate the hammers 40, 42 to allow the information to be taken of the number of strokes to be struck and to couple the striking barrel 24 to said parts used to actuate the hammers 40, 42 after the information has been taken to sound the strike.
  • the barrel drum 52 by its teeth 56, meshes with the wheel 104 of a unidirectional 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 around a point 114 and has a slot 116 in which a fixed pin 118 is engaged (visible at 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 being unwound by 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 release 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 asymmetric 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 sliding flange 60 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 train 50, also called the “small train”, which is a multiplier train.
  • the speed regulator 48 makes it possible to regulate the rotation speed of the striking train 50 and the barrel arbor 58.
  • a propeller 146 for locking and unlocking the striking train 50 is coaxial and integral with the speed regulator 48.
  • the output torque of the striking train 50 is very low, so that a simple tangent contact on the propeller 146 is sufficient to stop the entire striking 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 piece 150 as shown in Figure 11 .
  • the quarter piece 150 comprises 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 meshing with the quarter piece pinion 94.
  • the 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 basic movement. In addition, it carries a pin 164 which, with each revolution 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 pressed 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 subject 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 lifting 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 cause a lifting 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 rack of the hours 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 strike.
  • 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 of 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 step 0 of each branch of the minute snail when no minute is to be struck, in order to prevent the minute feeler from falling untimely 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 which 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 150 and minute 174 pieces 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 strike or an hour which slightly precedes an hour without a minute to strike, the quarter jumper 204 comes into contact with surprise 196 to shift it angularly in relation 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.
  • the minute piece 174 may be very close to the minute snail 170.
  • the time taken for the minute piece 174 to fall until it reaches the minute snail 170 may be too short to allow the hour rack 188 to activate the surprise 196.
  • the mechanism of strike 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 let the quarter jumper 204 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 then 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 36 ) engaged in the teeth of ratchet 226.
  • Ratchet 226 has twelve teeth and column stage 228 has six columns.
  • the active faces RM of the columns of 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 cams in the shape of a star for the inner wall 244 and of a generally polygonal shape for the outer wall 246.
  • the vertices RM of the star and of 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.
  • Each actuation of the selection pusher 20 moves the column wheel 224 by one ratchet tooth and switches the striking mechanism 6 from one operating mode to the other.
  • 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.
  • a secondary alarm triggering rocker 248 is used, pivoted around a point 250 and which carries at one end a first pin 252 and at another end a second pin 254 ( figure 20 ) engaged in the hollow 242 of the cap 230.
  • On the first pin 252 acts an alarm triggering rocker jumper 256 subjected to the action of a jumper spring 258.
  • the alarm triggering rocker jumper 256 has two inclined surfaces 260, 262 forming an angle between them.
  • the support of the first inclined surface 260 of the alarm triggering rocker jumper 256 on the first pin 252 keeps the second pin 254 in abutment against the outer wall 246 of the recess 242 in an RM zone and keeps the first pin 252 out of the turning path of a stop 264 defined by an extension 266 of the quarter piece 150 - stop 264 which is in a concentric arc with the quarter piece 150.
  • the quarter piece 150 is free to fall onto the quarter snail 160 upon actuation of the activation lock 22.
  • the secondary alarm triggering rocker 248 prevents a primary alarm triggering rocker 268 from touching an output cam 270 of an alarm differential 272, as will be explained later.

  • This device comprises a deactivation lever 448 coaxial with the time-setting lever 368, subjected to the action of a return spring 450 and controlled by the pull 366 and a locking lever 452 controlled by the deactivation lever 448.
  • the locking lever 452 When the winding stem 364 is in the axial pushed winding position ( figure 38 ), the locking lever 452 does not act on the primary alarm triggering lever 268 and the alarm part of the striking mechanism 6 can operate normally.
  • the winding stem 364 When, on the other hand, the winding stem 364 is placed in the axial position for setting the alarm time or in the axial position for setting the current time ( figure 39 ), the locking lever 452 pushes the primary alarm trigger rocker 268 so as to move the lug 288 away from the output cam 270, thereby preventing the alarm from triggering.
  • the present invention has been described above in the context of a minute repeater. But it is clear to those skilled in the art that it can be applied to any other repeater, for example a quarter or five-minute repeater.
  • the minute repeater function or, more generally, repeater could be part of a grande or petite sonnerie mechanism that the timepiece would include.
  • the activation lock 22 could be replaced by a rotating bezel or a pusher, as is known per se.
  • the lock and the rotating bezel are preferred to the pusher because they require less force from the user to arm the striking barrel 24.
  • the winding of the striking barrel 24 by the control rack 112 could be carried out by the barrel shaft 58 rather than by the barrel drum 52.
  • the fusee 64, 68, 86, 90, 92, 94, 96 would be coupled by a kinematic link to the barrel drum 52 rather than to the barrel shaft 58.
  • Another modification could consist of controlling the quarter jumper 204 and/or the minute blocker 210 by a part other than the hour rack 188, for example by the quarter part 150.
