Definitions

  • the present invention relates to a striking device for a mechanical timepiece; it also relates to a watch movement provided with such a device as well as a timepiece provided with such a movement comprising such a device.
  • Watchmakers have, at all times, introduced devices that allow the ringing of hours in their timepieces. Especially for portable timepieces, whether it is a pocket watch, a wristwatch or other portable piece, a complication is to introduce a ring of hours to repetition.
  • Various devices have been proposed for this purpose, comprising a plurality of levers and cams to enable the desired function to be achieved.
  • the setting of the ring is generally independent of that of the clockwork, respectively that of the display of hours.
  • a carillon timepiece equipped with a striking mechanism comprising, arranged on the axis of the center, four cams of quarters, intended to cooperate with parts of quarters, and a snail and a surprise minutes intended to cooperate with a minute room.
  • the striking mechanism further includes a clock striking mechanism.
  • the object of the invention is therefore to propose a striking device for a timepiece free from the known drawbacks of the devices of the prior art, in particular whose time to ring corresponds exactly to the time displayed, whatever either the positive or negative setting on the latter, a setting made during ringing that does not cause damage and is relatively easy to debug, adjust and use.
  • This device is less complex than the known devices, it will be less expensive.
  • the figure 2 shows a portion of the device for determining the time to ring.
  • the axis 1, carrying the wheel 101 makes 1 turn in 1 hour, clockwise; its rotation is controlled by the movement of the timepiece schematized in 100 on the figure 1 .
  • the single tooth of the wheel 101 operates, 1 time per hour, an intermediate gear 201, which increments, clockwise, the wheel 3001 (48 teeth) of 1 / 24th of a turn every hour.
  • the figure 3 shows the ringer drive in the non-ringing position.
  • This device comprises an axis 4 carrying a plate 407 provided with a pin 41, and an intermediate gear 402 meshing with an intermediate wheel 502 integral with a pinion 503 meshing on a hammer wheel 603. The latter meshes with a part on a drive wheel 803 and secondly on a control pinion 703.
  • a control cam 907 mounted on the axis 9 in connection with a pinion of the axis 7 d a manner which will be described below, as well as the bulkiness shown in broken lines of a wheel mounted on the axis 31.
  • a ringing barrel schematized in 69 on the figure 1 supplies the device with energy, preferably via its axis 6.
  • the axes 7 and 9 each carry a pinion, respectively 706 and 906 of each 12 teeth, continuously engaged together, making these two axes are simultaneously stationary or rotating.
  • the axis 7 additionally carries a first control gear 705 provided here with 4 teeth out of 8, capable of being actuated by a wheel 3105, provided with 2 teeth in opposition, mounted on the axis 31.
  • the axis 9 carries likewise a hammer lock cam 908 which, in its position shown in the figure, blocks the striking hammer 90 in the locked position, preventing any ringing.
  • the knocking wheel 608 of 12 teeth whose rotation described below, will drive the hammer 90 to hit the hours. This striking wheel 608 is at a different meshing level than the first control gear 705; contrary to what the figure might suggest, there is never any meshing between these two elements.
  • the striking device is locked in the non-ringing position, the control rocker 60 being locked in the non-ringing position by its arm 62 in relation to the cam 907, blocking thus the rotation of the train, by the pin of the plate 407 engaged by the arm 61, and by moving the axis 8 by the arm 63, so that none of the wheels carried on this axis can mesh with a wheel carried by the shaft 31.
  • the position of the first drive gear 705 passes the teeth of the wheel 3105 along its movement increments of 1/24 of a turn every hour in the clockwise direction , described next to the figure 2 . In this position of the control rocker 60, there is therefore no interaction between the watch movement itself and the striking device.
  • the figure 5 shows the same elements as those of the figure 3 , but in the ring start position.
  • the control flip-flop 60 has rotated a fraction of a turn clockwise, under the action of a current time ringing command provided by the watch movement 100 or by a ringing command of the clock. hour in passing, provided by a push button on the housing of the timepiece, these two commands being symbolized by the arrow A in the figure.
  • the rotation of the hammer wheel 603 drives the control pinion 703 which pivots a portion of a turn before stopping since it has no more teeth in front of the wheel 603.
  • the figure 7 shows the same elements as those of the figure 4 , but in the ring start position.
  • the pins 7 and 9 have rotated a turn portion and then stopped, causing the first drive gear 705 to be in a position ready to receive the tooth of the wheel 3105 in a counter-clockwise rotation driven according to the movement of the wheel 3104 mentioned above, while the cam 908 has also rotated a portion of a turn, releasing the hammer 90.
  • the knocking wheel 608 in rotation now controls the ringing of the hammer 90.
  • the figure 8 shows the same elements as those of the figure 7 , but in the position of preparation of end of ring.
  • the wheel 3105 has continued to rotate counterclockwise so that one of its two teeth engages and meshes with the first drive gear 705. This meshing controls a pivoting of the axis 7, then of the axis 9, via the pinions 706 and 906, described with respect to the figure 4 .
  • the cam 908 is still in the position to let the hammer 90 ring the hours under the action of the striking wheel 608.
  • the figure 9 shows that following the pivoting movement of the axes 7 and 9 mentioned above, the pinion 703 comes into meshing with the wheel 603, the rotation of the axes 7 and 9 and the gears and cams they are now being ordered by this last meshing.
  • the figure 10 is similar to the previous one, just a moment later; it is seen in particular that the arm 62 of the flip-flop 60 will soon leave the upper portion of the cam 907 to join its recessed portion.
  • the figure 11 shows the elements of the figure 8 at the same time as the one represented at figure 10 .
  • the first drive gear 705 is now clear of the wheel 3105 and the cam 908 is in position just before blocking the movement of the hammer 90.
  • the device is in the same position as shown in FIGS. figures 3 and 4 , the cam 907 maintaining the rocker 60 in the non-ringing position, is remote the axis 8 of the axis 3, so as to disengage the wheel 804 of the wheel 3104, and again blocked the rotational movement of the axes 4 , 5, 6 and 8 by engaging the pin 41 of the plate 407 by its arm 61.
  • the duration during which the hammer strikes the hours, respectively the number of hits is a function of the angle ⁇ represented at the figure 7 corresponding to the path to be traveled by a tooth of the wheel 3105 between the moment when the ringing is triggered, and that where the cam 907 pushes the arm 62 of the rocker 60 to interrupt the ring.
  • this angle increases by 1 / 24th of a turn every hour.
  • the gear ratio between the wheel 3105 and the wheel 608 is calculated in such a way that an angular rotation of 1/24 th of a revolution of the wheel 3105 corresponds to the passage of a tooth of the wheel 608, respectively at the moment of striking. a ringing sound.
  • the buzzer can be controlled either by the watch movement, in which case it is controlled just after the wheels 3001, 3104 and 3105 have incremented by a 24 th of a turn, or at the request of the user, in which case the number of hits corresponds to the time passed.
  • the wheel 101 has been described having a tooth and performing 1 turn in 1 hour. It could equally well comprise 12 teeth and perform a revolution in 12 hours or any number of teeth, its rotational speed being adapted so that the wheel 3001, respectively the axes 30 and 31 are incremented by 1 / 24 th turn every hour.
  • This wheel 101 directly related to the time display, therefore follows the settings of this time display, for example during a passage of time zone or during a transition from winter time to the time of day. summer or vice versa, thus directly modifying the angle ⁇ mentioned previously, thus directly adjusting the buzzer.
  • the positioning means 32 mentioned may include one or more connecting gears so as to perform the operations and functions described.
  • the decoupling of the axes 30 and 31, as previously described or as proposed above alternatively allows a ring setting even when it is ringing, without damaging any part of the device.
  • the directions of rotation, number of gears, wheels, numbers of teeth described can be adapted according to the configurations encountered, so as to fulfill the function or functions mentioned. It can be seen that the striking device essentially comprises wheels and gears; it is therefore relatively simple to manufacturing, easy to develop, adjust and use. Such a device is relatively less expensive than a device corresponding to levers and cams.
