Definitions

  • the present invention relates to the field of watchmaking and more specifically relates to a display device for a timepiece.
  • the invention relates to a display device for a timepiece, driven by a base wheel of a watch movement, controlling the display of an indication member so that the latter displays, at the request, information relating to the current time or information concerning the operation of the timepiece.
  • base wheel of the watch movement means any wheel intended to control via the device a needle, a disk or any time indicating mechanism, including any wheel intended to control the display of seconds, minutes, hours, date, day, week, month, phases of the moon, year or years, or any indication relating to the operation of the timepiece, such as by example, the power reserve.
  • the on-demand display device is characterized by the fact that it comprises a cam having a periphery of predefined shape and intended to be driven by the base wheel, a rocker intended to be pivotally mounted, with reference to a frame element of the watch movement, between a waiting position, associated with a rest position of the display member, and a stop position, associated with a position indicating the display member, the rocker carrying a feeler finger intended to cooperate with the periphery of the cam to define the stop position, the rocker further carrying a rake arranged in engagement with a pinion for driving the display member.
  • the device further comprises elastic means exerting a force on the rocker to tend to position it in the waiting position, and a control lever arranged to neutralize the elastic means in response to the action of a wearer. the timepiece and allow the rocker to position itself in the stop position to display the desired information.
  • the base wheel is the floor controlling the display of the minutes and the device is driven by a second base wheel of the timepiece, which is the hour wheel, which causes a second cam, a second lever, also maintained in the waiting position by a second spring, being actuated manually on demand by means of the same pusher systematically controlling the two levers so as to rotate on its axis a second rake, until the moment where a finger of the second rake abuts on the second cam.
  • the second rake drives a second pinion carrying a second time indicating member, the cams having a configuration corresponding to the following minutes, respectively hours to display.
  • Each of the base wheels can transmit the rotational movement to the corresponding cam via a gear meshing with a wheel integral with the cam, the base wheels running one revolution in one hour, respectively in twelve hours.
  • the display device provides a mysterious character to the timepiece it equips. Moreover, it also makes it possible to disengage the dial and to improve the readability of other displayed information than that displayed by the indicator organs driven from the device.
  • the time indicating members may be needles, discs or any device arranged to indicate the seconds, minutes, hours, date, day, week, month, phases of the moon, year , etc., or a piece of information relating to the operation of the timepiece.
  • the pinions attacked by the rakes are preferably coaxial, the rakes being advantageously placed on either side of the corresponding axis, each pinion carrying an indicator needle.
  • the two needles of the timepiece can be placed at noon when the levers controlling the rakes are in the waiting position.
  • the drawing represents, by way of example, an embodiment of the on-demand display device for a timepiece in which:
  • FIG. 1 is a front view of an example of a timepiece comprising a display device according to the invention and in which are visible in particular two needles, minutes and hours, in the rest position twelve hours before the pusher is activated,
  • FIG. 2 is a simplified top view of an exemplary embodiment of the display device according to the invention for displaying, on demand, the minutes and the hours when the pusher is actuated, and
  • FIG. 3 is a simplified perspective view showing the operation of rakes placed at different heights, so as to attack the superposed gears carrying the needles.
  • the timepiece 1 represented in the Fig. 1 comprises a conventional winding 2 located to the right of its housing 3 and a pusher 4 for controlling the display on demand of minutes and time placed to the left of the housing.
  • the minute and hour indicating hands 5, 6 are placed on twelve hours when the pusher 4 to the left of the housing is not actuated. From the moment the pusher is pressed, the device is actuated and the current minutes and hours are indicated as explained further in connection with the Fig. 2 and 3 .
  • Fig. 2 and 3 On the lower and the right, respectively, Fig. 2 and 3 , there is shown a first part 10 of the display device which provides the indication of the minutes, while the part 30 of the display device which provides the indication of the hours is placed at the top and to the left, respectively, of the Fig. 2 and 3 .
  • a base wheel 11 which transmits the movement of the finishing gear train (not shown for the sake of clarity) of the timepiece to a gear 12 which drives a wheel 13 secured to a cam 14 by being coaxial therewith, the ratio corresponding gear being such that the cam performs one revolution in one hour.
  • a first lever 15 for actuating the display device is pivotally mounted, along an axis 16, on the frame of the movement.
  • This lever comprises a spring stop 17 on which a spring 18 acts to hold the lever in a waiting position which is that visible in the figures.
  • the lever comprises a first end 19 intended to undergo a pressure force resulting from the actuation of the pusher 4, manually actuated at the request of the outside of the timepiece.
  • the lever further carries a pin 20 at its second end.
  • rocker 22 This is arranged to act on a spout 21 of a rocker 22 pivotally mounted on the frame of the movement along an axis 23 located near the spout.
  • the rocker 22 also carries a rake 24 and a feeler finger 25 intended to cooperate with the periphery of the cam 14.
  • the rocker 22 is arranged on the movement in such a way that the rake 24 can mesh with a pinion 26, arranged here at the center of the movement, itself engaged with a return system comprising a gear 27 meshing with a wheel 28 secured to a first end a spring 29 prestressed spring and whose second end is secured to the frame of the watch movement.
  • the pinion 46 which is intended to carry the hour hand 6, is driven until the needle indicates the current time, because of the configuration of the cam 34 defining the angular amplitude of the rotation of the latch 42 at this moment, with reference to its waiting position.
