Definitions

  • the present invention relates to a timepiece comprising a striking mechanism combining a repeater mechanism, indicating the current time by sound on demand, and an alarm or clock mechanism.
  • Such a timepiece is described in the patent CH 703635 of the present plaintiff.
  • the alarm mechanism it comprises uses the quarter and minute parts and the hour rack of the repeater mechanism to sound the alarm time, but holds them back before they come into contact with their snails. respectively until the current time coincides with the alarm time programmed by the user.
  • First and second pushers present on the case of the timepiece allow the user to respectively activate the repeater mechanism, to ring the current time, and the alarm mechanism.
  • the snooze 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 drawback of requiring, as a source of energy for the repeater and alarm mechanisms, a striking barrel that can be wound by a winding crown.
  • This barrel must be able to store a large amount of energy, therefore be large in size, to avoid the user having to wind it often.
  • it requires in practice to provide a display of its energy reserve so that the user can know when to wind it up, and the user must remember to check the energy level before activating the repetition or the alarm.
  • the present invention aims to provide a repeater and alarm timepiece which overcomes, at least in part, the aforementioned drawbacks and which is easy to use.
  • a timepiece in particular a wristwatch, a pocket watch, a pendant watch or a clock, comprising a striking mechanism that can operate in a repeat mode or an alarm mode, a source of mechanical energy 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 repeat mode is activated and to produce at an hour alarm determined 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 making it possible to select one or the other of the repeat and alarm and a second manual control device for arming the mechanical energy source and activating the selected mode.
  • the energy source As the energy source is armed before each chime, it can be small, like the barrels of traditional repeater mechanisms without an alarm.
  • the arming of the energy source is transparent for the user, since it is the same control member, preferably a lock, which allows this arming and the activation of the repeat or alarm mode. It will also be noted that the fact of activating the repeat mode and the alarm mode by means of the same control member provides simplicity of use.
  • a timepiece which in the example illustrated 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 seconds indicator hand 14 actuated by the basic movement, as well as an hour hand d alarm 16.
  • the winding crown 18 can occupy three axial positions: a pushed position, an intermediate position and a pulled position. In the pushed position, a clockwise rotation of the winding crown 18 winds the basic movement. In the intermediate position, a rotation of the winding crown 18 clockwise or anti-clockwise allows an alarm time to be set. In the pulled out position, a rotation of the winding crown 18 clockwise or anti-clockwise allows the current time to be set (time of the base movement).
  • the selection pusher 20 passes coaxially through the winding crown 18 and is axially movable with respect to the latter. The selection pusher 20 could nevertheless be separated from the winding crown 18.
  • the striking mechanism has a minute repeater operating mode and an operating mode alarm, the passage from one mode to the other being effected by means of the selection button 20.
  • an actuation of the activation lock 22 that is to say a sliding of the activation lock 22 on the periphery of the case 2 between a rest position and an end position , switches the striking mechanism 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.
  • a selected minute repeater state block a
  • an activated minute repeater state block b
  • an actuation of the activation lock 22 causes the ringing mechanism to pass from a selected alarm state (block c), where the ringing mechanism is inactive, to an activated alarm 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 sounded, the alarm mechanism returns to its selected alarm state (block c).
  • Said determined alarm time may be an alarm time programmed by the user, indicated by the alarm hour hand 16, or an alarm time depending on an alarm time programmed by the user.
  • the alarm time can only be set by the user in steps of fifteen minutes over twelve hours, either at the full hour, the hour and a quarter, the hour and a half or the hour. hour and three quarters, and said determined alarm time at which the bell is triggered is the alarm time programmed by the user less one or two minutes, in order to increase the number of strokes to ring and make the time indication particularly audible to the user.
  • the user can, by pressing the selection button 20, return to minute repeater mode where he can ring the current time at any time by activating the activation lock 22.
  • minute repeater or alarm it is not possible to stop the chime when it has been triggered. The user must wait for the end of the chime before being able to carry out a new maneuver on the timepiece.
  • the travel 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.
  • the two modes of operation use the same energy source consisting of a striking barrel 24 (cf. picture 2 ) independent of the barrel of the basic movement.
  • the base movement and the striking mechanism are mounted on a frame (not shown) conventionally formed of a plate and bridges.
  • the basic movement (not shown) is of the traditional type. It is located on the bridge side and comprises a barrel acting as a power source, a going train, an escapement and a balance-spring or other resonator.
  • the basic movement can be supplemented by an automatic winding mechanism arranged to wind the barrel using the energy released by the movements of the wearer of the timepiece.
  • the striking mechanism designated by 6 in the drawings, is located partly on the bridge side and partly on the dial side, but mainly on the dial side.
  • the rest of the striking mechanism 6 (cf. figure 12 ) is located on the dial side.
  • the striking barrel 24 (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 free rotation manner, by a barrel arbor 58 to which is attached the inner end of the barrel spring 54, the outer end of the barrel spring 54 being itself coupled to the wall of the barrel drum 52 by a sliding flange 60, as will be explained later.

  • a trigger ratchet 64 free in rotation relative to the barrel arbor 58 and that a spring 66 (visible at figure 27 ) prevents backsliding
  • 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 of the trigger ratchet 64 to be threaded into the drive plate 68.
  • the elongated holes 72 permit limited rotation of the detent ratchet 64 relative to the drive plate 68.
  • the drive plate 68 carries a detent pawl 74 and a return spring 76 of the trigger pawl.
  • a pin 78 carried by the trigger ratchet 64 passes through an opening 80 of the drive plate 68 large enough not to impede the rotation of the latter. This pin 78 has the function of causing the trigger pawl 74 to move outwards, the end of which has an inclined surface 82 for this purpose.
  • the trigger pawl 74 is arranged to cooperate, via an engagement lug 84 which it comprises, with a barrel ratchet 86 free to rotate around a barrel 88 of the escape plate 68.
  • a ratchet of 90 hours Around the barrel of the ratchet to barrel 86 are mounted a ratchet of 90 hours, a rack pinion on rocket 92, a piece pinion of quarters 94 and a piece control finger quarters 96.
  • the hours ratchet 90, the rack pinion on the fusee 92 and the quarters part control finger 96 are integral in rotation with the barrel ratchet 86.
  • the quarters part pinion 94 is free in rotation relative to the barrel ratchet 86 but is controlled by the quarters piece control finger 96 via a pin 98 carried by the quarters piece pinion 94.
  • the assembly 64, 68, 86, 90 , 92, 94, 96 is held axially in one direction by a shoulder 100 of the barrel shaft 58 against which the drive plate 68 can rest 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 fuse wheel 62 are located on the bridge side.
  • the assembly 64, 68, 86, 90, 92, 94, 96 constitutes a detent fuse of the type found in grand alarm mechanisms where the alarm can be triggered manually (on demand) or automatically (by the way). It makes it possible to decouple the striking barrel 24 from the parts used to actuate the hammers 40, 42 to authorize the taking of information of the number of strokes to be sounded and to couple the striking barrel 24 to the said parts used to actuate the hammers 40, 42 after taking information to ring the bell.
  • 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 disengageable pawl system, is engaged with a toothed sector 110 of a control rack 112 operable by the activation lock 22.
  • control 112 is pivotable around a point 114 and has a slot 116 in which a fixed pin 118 is engaged (visible at the figure 27 ) acting as a stop defining two limit positions of the control rack 112, namely a rest position and an end position.
  • a rack return spring 120 acts on the control rack 112 for the maintain in its rest position when it is not actuated by the activation lock 22.
  • the control rack 112 is used to arm the barrel spring 54 via the barrel drum 52.
  • a pawl 122 engaged in the toothing 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 also 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 in 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 wheel set 106 are integral in rotation in one direction and free in rotation with respect to each other in the other direction.
  • the movement of the control rack 112 by the activation lock 22 rotates the pinion 108 in the direction in which it is integral with 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 raises the striking barrel 24.
  • control rack 112 is abandoned to the action of its spring 120 and returns to its rest position by rotating pinion 108 but not wheel 104 which, in this sense, is disengaged from pinion 108 and retained by toothing 56 itself retained by 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 an abutment of the box 2 and an end position of race where it bears against the control rack 112 itself at the end of the race 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 plaintiff.
  • 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 loose 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 clicks 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 is actuated. 22, this in order to guarantee sufficient energy for the maximum number of strokes that the striking mechanism 6 may have to ring according to the alarm time that the user has programmed.
  • This sliding flange 60 is shown in figure 10 . It may comprise protrusions 144 cooperating with corresponding notches made 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 spindle wheel 62 is kinematically connected to the speed regulator 48 via the ring gear 50, also called the “small gear”, which is a multiplier gear.
  • the speed regulator 48 makes it possible to regulate the speed of rotation of the striking wheel 50 and of the barrel arbor 58.
  • a helix 146 for locking and unlocking the striking wheel 50 is coaxial with and integral with the speed regulator 48.
  • the output torque of the striking wheel 50 is very low, so that a simple tangent contact on the helix 146 suffices to stop the entire striking wheel 50 and the barrel arbor 58. This tangent contact is ensured by a lever propeller stopper 148 when the latter is constrained by a quarter piece 150 as shown in figure 11 .
  • the quarter part 150 comprises on its periphery two series 152, 154 of three teeth.
  • the first series 152 is intended to drive a first raising of the quarters (not represented) raising a small hammer 42 striking a high pitch 46 (cf. figure 11 and 3 ), and the second series 154 is intended to drive a second lifting of the quarters (not represented) raising a large hammer 40 striking a low gong 44.
  • the part of the quarters 150 also has an internal toothing 156 in engagement with the pinion of the part quarters 94.
  • the piece quarters 150 still has a quarters feeler 158. This quarters feeler 158 is arranged to rest on the rungs of a quarters cochlea 160 (cf.
  • the quarter cochlea 160 is coaxial with the floor of the basic movement. In addition, it carries a pin 164 which, at each turn of the roadway, advances a twelve-pointed star 166 carrying a cochlea of hours 168 by one tooth.
  • the barrel ratchet 86 In the rest state of the striking mechanism 6 ( selected minute repeater state or selected alarm ), 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 helix 146 in a raised position, away from the quarters cochlea 160, against the force of the quarters piece return spring 162.
  • a cochlea of 170 minutes (cf. figure 14 ) is coaxial with and integral with the roadway. On the rungs of this 170-minute cochlea can come to rest a 172-minute feeler of a 174-minute piece to determine the number of minutes to strike.
  • the minute part 174 is mounted on the same axis 176 as the quarter part 150 and is subjected to the action of a minute part return spring 178.
  • the minute part 174 is provided with a first toothed sector 180 of fourteen teeth intended to cause lifting of the minutes lifting the small hammer 42.
  • the minute part 174 comprises a second toothed sector 182 which cooperates in a traditional manner with a minute hook 184 carried by the quarter part 150 .
  • the 90-hour ratchet is intended to drive a lifting of the hours raising the large hammer 40.
  • the rack pinion on a rocket 92 integral with the 90-hour ratchet, meshes with the toothed sector 186 of a 188-hour rack or rake ( see figures 4 to 6 and 12 ) subjected to the action of a rack return spring for the hours 190 and which comprises a feeler for the hours 192 capable of coming to bear on the rungs of the cochlea for the hours 168 to determine the number of hours to strike.
  • a pin 194 carried by the quarter piece 150 is used to retain the hour rack 188 for a certain time during the fall of the quarter piece 150 towards the quarter cochlea 160.
  • the cochlea of quarters 160 and the cochlea of minutes 170 is freely mounted a surprise 196.
  • a pin 198 (cf. figure 12 and 14 ) implanted in the minutes cochlea 170 and engaged in a larger hole 200 of the surprise 196 limits the rotational mobility of the surprise 196 with respect to the minutes cochlea 170.
  • the quarter cochlea 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 cochlea 170.
  • the function of a surprise is to lengthen the 0 rung of each arm of the minute cochlea when no minute is to strike, in order to prevent the minute feeler from falling untimely on the fourteenth rung of the adjacent branch.
  • the surprise 196 is activated before each striking, when the hour to strike is an hour without a minute to strike or an hour which slightly precedes (typically by one or two minutes) an hour without a minute to strike, by a quarter jumper 204 which shifts it angularly with respect to the minutes cochlea 170 against the action of the spring 202. After the ringing, the surprise 196 returns to the rest position.
  • the activation of the surprise 196 does not occur during the actuation of the activation lock 22, as in a classic minute repeater, but during the fall of the parts of the quarters 150 and the minutes 174 and of the hour rack 188 on 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 cochlea 168, it allows the quarter jumper 204 to approach the surprise 196.
  • This movement of the quarter jumper 204 has most of the time no effect on the surprise 196 given the angular position of that here, but when the hour to strike 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 the surprise 196 to shift it angularly with respect to the minute cochlea 170.
  • the quarter jumper 204 is only in the way of the surprise 196 during the striking phase and does not need to be raised every quarters of an hour by the surprise 196 between the moment when the alarm is activated by the actuation of the activation lock 22 and the moment when the current time coincides with the determined alarm time. Energy consumption is thus reduced.
  • the 174 minute coin may be very close to the 170 minute cochlea.
  • the time it takes for the 174 minute coin to fall to the 170 minute cochlea may be too short to allow the 188 hour rack to activate the 196 surprise.
  • the mechanism of chime 6 is provided with a 210 minute blocker arranged to delay the fall of the 174 minute piece until the 196 surprise is activated by the 188 hour rack.
  • the 210 minute blocker is particularly noticeable at the figure 14 . It pivots around a point 212 and its rest position is defined by a pin 214 against which it presses 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 during the fall of the quarter piece 150, the minute piece 174 and the hour rack 188.
  • 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 according to the hour to strike. This cooperation between the 188 hour rack and the 210 minute blocker raises the 210 minute blocker and releases the 174 minute piece which can thus fall on the 170 minute cochlea to take the information of the number of minutes to ring.
  • the striking mechanism 6 includes (cf. figures 15 to 20 ) a column wheel 224 consisting of a ratchet 226, a stage of columns 228 and a cap 230, these three elements 226, 228, 230 being mounted integrally around a column wheel axis 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 rocker 236, a control 238 and a control hook 240 (more visible at the figure 36 ) engaged in the teeth of the ratchet 226.
  • the ratchet 226 has twelve teeth and the floor of columns 228 six columns.
  • the active faces RM of the columns of the stage of columns 228 correspond to the minute repeater mode while the voids AL between two columns correspond to the alarm mode.
  • the cap 230 is located in the example illustrated between the ratchet 226 and the stage of columns 228. It has in its lower face, that is to say the face farthest from the stage of columns 228, a recess 242 which surrounds the column wheel axle 232.
  • the two walls which laterally delimit the recess 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 aligned angularly 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 causes the striking mechanism 6 to pass from one mode of operation to another.
  • the principle of operating mode selection is to allow quarter coin 150 to drop immediately after actuation of activation lock 22 when striking mechanism 6 is in minute repeater mode, to trigger the striking hours, quarters and minutes of the current time, and to prevent the quarters piece 150 from falling beyond an intermediate standby position, until the current time corresponds to the determined alarm time, when the striking mechanism 6 is in the alarm mode.
  • a secondary alarm trigger rocker 248 is used pivoted around a point 250 and which carries at one end a first pin 252 and at the other end a second pin 254 ( figure 20 ) engaged in the recess 242 of the cap 230.
  • On the first pin 252 acts an alarm trigger rocker jumper 256 subjected to the action of a jumper spring 258.
  • the alarm trigger 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 trigger rocker jumper 256 on the first pin 252 keeps the second pin 254 bearing against the outer wall 246 of the recess 242 in an RM zone and keeps the first pin 252 out of the gyration path of a stop 264 defined by an extension 266 of the quarter piece 150 - stop 264 which is in an arc of a concentric circle with the quarter piece 150.
  • the quarter piece 150 is free to fall on the quarter cochlea 160 as soon as the activation lock 22 is actuated.

  • the winding of the striking barrel 24 by the control rack 112 could effected by the barrel arbor 58 rather than by the barrel drum 52.
  • the fusee 64, 68, 86, 90, 92, 94, 96 would be coupled by a kinematic connection to the barrel drum 52 rather than to the barrel arbor 58.
  • Another modification could consist in controlling the quarter jumper 204 and/or the minute blocker 210 by a part other than the hour rack 188 , for example by the piece of quarters 150.
