Definitions

  • the present invention relates to a chronograph watch.
  • the manufacturer who plans to transform an existing watch movement in order to adapt a chronograph is obliged to adapt its construction to the caliber it has chosen, so that the design and production, in particular the tools, are only suitable for one size and must be repeated for each size to be fitted.
  • the object of the invention is to provide a means of easily adapting a chronograph to a clockwork movement, the chronograph part of the watch being able, without appreciable modifications, to be applied to one caliber or another.
  • the watch shown generally designated by 1, comprises a usual clockwork movement 2, round in the particular case, driving the ordinary hour hands, namely an hour hand 3, a minute hand 4, and a seconds hand in the center 5.
  • the box of this mount includes a middle-bezel 8, a crystal 9 and a base 10 (fig. 4).
  • Watch 1 further comprises a chronograph mechanism carried by a frame independent of the frame of movement 2.
  • the frame of this movement or chronograph module is shown diagrammatically in FIG. 2 where only the "plank” parts of this frame have been shown, excluding the parts forming spacers, such as pillars or columns.
  • This frame includes a base plate 11 and an upper plate 12, as well as an annular bridge 13, constituting a cage in the general shape of a bell, which covers the clockwork movement 2, the annular part of this frame encircling the movement. 2.
  • the intermediate plate 14, to which the base plate 11 of the frame of the chronograph module is fixed, will itself be fixed to the plate of the clockwork movement 2 in place of the dial thereof, and by the same means, for example using feet that it will present for this purpose. These feet may only be used for positioning (centering, orientation) of the intermediate plate on the stage of movement 2, the fixing itself being carried out using screws taking in the holes of the stage of movement provided for the movement fixing keys in the box. It will then be the plates 11 or 12 of the frame of the chronograph module which will carry the keys for fixing the assembly in the box.
  • the chronograph module has three indicators, namely a hand at the center 15 of the chronograph, beating the 1/5 of a second, a hand 16 counting the hours, turning opposite a lap of hours 17 presented by the dial of the watch, desi hindered by 18, and a minute counting hand 19, rotating opposite a minute revolution 20 that also has dial 18.
  • This resting on the plate 12 (figs. 4, 5 and 6), is fixed by feet 21 which extend to the level of the plates 11 or 12 (fig. 3).
  • the annular bridge 13 of the frame of the chronograph module carries three electric motors 23, 24 and 25 respectively driving the three hands 15, 16 and 19.
  • These three motors 23, 24 and 25 are controlled by a quartz oscillator 26 and are powered by a common battery 27 (fig. 3), the desired frequency divisions being ensured by an integrated circuit 28.
  • the module comprises a printed circuit 29, the annular plate of which is superimposed on the annular bridge 13 of the frame of this module.
  • the three motors, the quartz oscillator, the battery, the integrated circuit with, in addition, a variable capacitor (trimmer), indicated at 30 in fig. 3, are all located around watch movement 2.
  • the chronograph hand 15 is driven by the motor 23 as follows:
  • the rotor of the motor 23, designated by 31 (figs 3 and 5), is integral with a pinion 32 driving, by means of two mobiles 33 and 34, a wheel 35 connected, by means of a coupling to friction comprising a cambered washer 36, to a pinion 37 engaged with a wheel 38 secured to a sleeve or barrel 39 surrounding the hour barrel wheel, designated by 40 of the clockwork movement 2 (figs. 2 and 4).
  • This barrel 39 carries the chronograph hand 15.
  • the entire gear train connecting the rotor of the motor 23 to the hand 15 is thus carried by the central part of the frame of the chronograph module, covering the clockwork movement 2, and not by the annular part of this frame, surrounding the movement.
  • the friction between the wheel 35 and the pinion 37 is intended to allow manual reset of the needle 15 without being requested from the motor rotor.
  • the wheel 38 secured to the barrel 39 is engaged with a wheel 41 (FIG. 3) secured to a reset heart 42 with which a reset hammer 43 cooperates, including one only a very small part has been shown in fig. 3, controlled by a reset push-button 44 acting on a part folded at a right angle 43 a of the rocker having the hammer 43 (figs. 1 and 4).
  • a reset push-button 44 acting on a part folded at a right angle 43 a of the rocker having the hammer 43 (figs. 1 and 4).
  • the hand 19 of the minute counter is driven by the motor 25 as follows:
  • the rotor, designated by 48 (fig. 6), of the motor 25 is integral with a pinion 49 driving, by means of a mobile 50, a wheel 51 whose shaft, designated by 52, carries the needle 19.
  • the hand 16 of the hour counter is driven by the motor 24 in a similar fashion:
  • the rotor, designated by 53 (fig. 3), of the motor 24 is integral with a pinion 54 driving, by means of a mobile 55, a wheel 56 whose shaft, designated by 57, carries the needle 16.
  • the reset of the hands 16 of the hour and 19 minute counter will be carried out electronically, controlled by the push-button 44.
  • the reset of the various chronograph indicators is mixed, the chronograph hand 15 being reset mechanically and the hands of the counters 16 and 19 being electronically. Note that resetting the counters could also take place. mechanically kill, using hearts which would then be actuated by hammers which could consist of additional purlins of the same scale as that presenting the hammer 43.
  • the watch described and shown further comprises a date indicator constituted by a hand 58 rotating opposite a date turn 59 carried by the dial 18, and an indicator of the moon phases constituted by a disc 60 visible through a window 61 of the dial.
  • the intermediate plate 14 carries the needle 58 of the date while the wheel 66 carries the disc 60 of the moon phases.
  • the intermediate plate 14 could carry still other indicators.
  • annular used to define the particular shape of the frame of the chronograph module does not imply that this frame is necessarily circular. Indeed, the basic movement could be in shape, the annular frame of the chronograph module then being of corresponding shape so as to surround it.
  • the basic movement 2 does not undergo any other modifications, to be completed by a chronograph, than the lengthening of the barrel 40 of the hour wheel, of the roadway, designated by 67, bearing the 4 minutes hand, and tigeron 68 of 5 seconds hand in the center.
