Definitions

  • Watches and timepieces are also known in which at least one time indicator member is constituted by a disc made of transparent material comprising an external toothing serving to drive it by a pinion. These are relatively large pieces by which we essentially seek a particular effect of the time display.
  • the object of the present invention is to produce a watch which differs radically from these known watches by making it possible to produce a watch of high precision which, while being composed of easily machinable elements and ensuring high reliability, can be thinner than all known flat watches.
  • a watch having the characteristics of the preamble of claim 1 is known from document FR-A-1 085 277.
  • Figures 1 and 2 of the drawing represent respectively, a plan view of the indicator members and the area of the finishing gears, the escapement and the balance and, a plan view of the same indicator members and the area of the mechanism winding and setting the time, an embodiment.
  • Figures 3 and 4 show in section, successively, the center of the watch with the indicator and motor members, then the finishing gears, the escapement and the balance wheel.
  • Figures 5 and 6 show in section the winding and time-setting mechanism.
  • Figures 7 and 8 show two termination variants, each according to four separate projections.
  • the bottom 51 of the box is also shown, constituting also the base plate of the movement capped by the bezel-middle part 62 carrying the crystal 61.
  • a graduation of the timer and possibly some brand or decor inscriptions are transferred or deposited by metallization.
  • the surface generally constituting the dial is here constituted by the upper face of the hour disc 1.1. concentric to the glass and comprising an hour mark transferred or added in relief as well as a toothing on its periphery driving the gear train of finishing. This hour disc performs 2 rotations per day under the action of a barrel spring.
  • the 1.2 minute disc is made of transparent material, performs 1 rotation per hour and also includes a minute mark transferred or added in relief as well as a toothing on its periphery used for its training.
  • This disc can also be made of metal, but then it consists of an outer crown (invisible by the glass) connected to a central core by at least one arm constituting the minute marker and is obtained either by cutting or electroforming, this the latter making it possible to produce a very thin disc as well as very thin and very fine arms capable of creating a particular aesthetic of the switch and the "dial".
  • All the elements constituting the movement are located inside a rectangle inside which the hour indicator disc determines approximately a written circle separating two opposite zones occupied, one (fig. 1) by the train finishing gears, the escapement and the balance wheel, the other (fig. 2) by the winding and time-setting mechanism.
  • An intermediate gear 2 carried by the gear train 52 meshes with an intermediate pinion of the intermediate wheel 3 which meshes with the large medium pinion of the large medium wheel 4 meshing on the one hand with the minute disc 1.2 and on the other hand with the small medium wheel pinion small medium 5 which meshes with the second wheel pinion second 6 meshing with the escape pinion of the escape wheel of the escape wheel 7 actuating the anchor 8 located under the anchor bridge 53 and maintaining the oscillations of the balance wheel 9 located under the cock 54.
  • the winding mechanism proper comprises the winding crown 60.1 secured to the winding pinion 10.1 located under the mechanism plate 55.1 held by the key 56.1 and meshing with a ratchet crown 1.6 whose toothing is identical to that of the hour disc 1.1 under which it is arranged. Therefore the rotation of the winding crown, manually controlled, controls the rotation of the ratchet crown 1.6.
  • the time setting crown 60.2 can occupy two distinct angular positions, the first selecting the mechanism winding function, the second selecting the mechanism setting time function.
  • the time-setting cam 59 which is a solidiary of the time-setting crown, which it locks elastically in this position by a spout of the setting lever.
  • the time setting lever is located above the mechanism plate 55.2 held by the key 56.2 and is biased by a rocking spring housed in the recess of the winding pinion and acting so that the rocking beak setting the time resiliently presses the time setting cam.
  • the pawl 13 urged by the pawl spring 63 works with the teeth of the ratchet crown so as to allow rotation only in the one direction corresponding to the reassembly.
  • the angular movement of the time setting crown places the time setting cam in a position controlling the movement of the spout of the time setting rocker. in such a way that the time setting pinion simultaneously penetrates into the teeth of the ratchet crown and of the time setting disc, making them integral.
  • a particular beak of the time-setting cam acts on the pawl, the beak of which is released from the teeth of the ratchet crown which can then move back and forth.
  • the free time setting pinion working with the teeth of the ratchet crown and the hour disc has the effect of neutralizing the driving torque of the barrel spring because it acts on the one hand on a bung 1.3 secured to the hour disc 1.1 and on the other hand directly inside the ratchet ring so that its degree of winding is a function of the displacement of one of the parts relative to the other.
  • the two parts becoming integral, it is then possible, by acting on the winding crown, to angularly move the hour and minute discs without modifying the degree of winding of the barrel spring.
  • part of the gear train is driven to a mobile comprising a calibrated friction in order to slide in both directions.
  • a protrusion of the lever constitutes a particular reference 57.1 appearing under the glass.
  • the time-setting pinion releases the teeth of the ratchet crown and the hour disc while the pawl again limits the rotation of the ratchet crown in the single winding direction.
  • the barrel spring 64 is disposed between the hour disc and the bottom of the case and has its outer turn connected to the ratchet crown, possibly by a sliding flange when the maximum winding is reached so as not to drive the disc of the hours if the torque exceeds the setting friction at the time of finishing. It is possible to make a radial opening in the hours disc by which it is then easy to control the situation of the turns of the barrel spring determining the degree of winding or the power reserve.
  • the intermediate return is pivoted on an intermediate tenon driven into the gear train 52 which also carries all the upper bearings located, at least partially, in the same plane as the glass.
  • the lower bearings 3.2, 4.1, 7.1, respectively of the intermediate wheel 3, the large wheel 4 and the escape wheel 7 are driven into shaped holes (allowing the evacuation of cleaning liquids) closed off sealed by plugs 51.1 driven into the bottom of the box and of the same material before the termination and the decoration thereof.
  • the anchor bridge carries the lower bearings of the small medium 5 and second 6 wheels as well as the upper bearing of the anchor.
  • the small medium wheel is constituted by an axis around which the small medium pinion freely rotates, secured to a friction spring, the outer arms of which slide at a determined torque on the small medium wheel driven onto the shaft so that the assembly is integral when the watch is running and that, when setting the time, the small medium gear can rotate in both directions without driving or overloading the small medium wheel.
  • the cock 54 carries the upper bearing of the pendulum 9 which is also in the same plane as the ice as well as the snowshoeing.
  • the lower bearings 9.1 and 8.1 of the balance and the anchor are also designed so that they can be washed without disassembly and are also flushed out in the bottom of the box.
  • the counter-pivot of the balance is visible in the bottom of the box, which gives it a special character. It is interesting to note that this type of watch makes it very easy to adapt a gait correction system, acting on the racket and actuable from the bottom of the box.
  • the second wheel makes one revolution in thirty seconds.
  • the bridges are guided and assembled on the bottom of the box using guide tubes and screws, said tubes being driven either into blind holes in the box, or in holes passing through it in the same way as plugs or bearings.
  • the winding crown 60.1 is integral with the winding pinion 10.1 which drives the ratchet crown via the winding gear 11 freely pivoting around a lug of the mechanism plate 55.1 also serving as a bearing for the winding stem and supporting the latch 56.1 now holding it while the pawl 13 also pivots on a tenon of an identical mechanism plate 55.2 also serving to support an identical key 56.2.
  • This embodiment of the mechanism is particularly interesting by the fact that it separates the control members whose functions are easily identifiable and especially by the fact that it allows the standardization of certain supplies (rods, mechanism plate, key, joint) constituting mechanisms occupying little height (occupying practically approximately the lower half of the height of the case), which allows to widely use the volume of the middle-bezel located above the mechanisms to perform decorative bevels ( or milling) or embedding additional elements (coats of arms or initials, precious stones) without exceeding the upper face of the box.
  • the middle-bezel 62 comes to adjust elastically around the bottom of the box by means of a seal while box screws 66 ensure the assembly of the 'together.
  • box screws 66 ensure the assembly of the 'together.
  • the same box is noted in an identical manner but with the crystal 61 (and the switch) oriented as a function of the strap 65 in the extension of the transverse axis of the box.
  • the object of the invention essentially relates to the production of very flat watches, the particular aesthetics of this type of piece accommodates a marriage between the upper face of the watch and the crystal (and the disc of the hours) in order to use the entire surface for the design of the dial, bezel and bracelet, special shapes and decorations allowing a wide variety of shapes to be produced independently of the rectangular base of the movement.
  • this particular arrangement of the movement makes it possible to produce a watch ensuring chronometric performance, having a greater power reserve than known watches while being even flatter.
