Definitions

  • the invention relates to a clockwork display mechanism with variable geometry, comprising at least one elastic hand which comprises a first drive barrel secured to a first end of a flexible blade, and a second drive barrel secured from another end of said flexible blade, and having a display index which, in an unstressed free state of said elastic needle in which both said first barrel and said second barrel are not stressed and are distant from each other, is spaced from said first barrel and from said second barrel, the service position of said elastic needle being a constrained position where said first barrel and said second barrel are coaxial with each other around an output axis, said display mechanism comprising first means for driving said first barrel around said output axis, and second means for driving said two xth barrel around said outlet axis, said first drive means and second drive means being arranged to deform said flexible blade, by varying the angular position of said second barrel relative to the angular position of said first barrel around said axis of output, and to vary the radial position of said display index relative to said output axis.
  • the invention relates to a timepiece movement comprising at least one such display mechanism.
  • the invention relates to a watch comprising at least one such movement, and / or at least one such display mechanism.
  • the invention relates to the field of clockwork display mechanisms, and more particularly for timepieces with complications, the invention can be used both for static timepieces such as pendulums or clocks, and for watches, due to the small dimensions of the mechanism according to the invention.
  • the dials of many timepieces are not circular, and it is advantageous to have solutions allowing to occupy all the available surface, for an even better visualization.
  • variable geometry display mechanism makes it possible to break a certain monotony of the displays, and to make the display more lively, with different aspects depending on the time of the day, or according to particular time periods.
  • an AM / PM display can be simply provided by the shape of a needle, which has a first aspect during the twelve hours of the morning, and a second aspect during the rest of the day ; we can also distinguish day / night displays, time zone displays, or others.
  • Elastic needles, and display mechanisms comprising such elastic needles have been described in the documents EP2863274 , EP 3159751 , and EP18186552 , which disclose many variations.
  • the invention proposes to further simplify such a mechanism and to make it even more compact and economical to produce.
  • the invention relates to a clockwork display mechanism with variable geometry, according to claim 1.
  • the invention relates to a timepiece movement comprising at least one such display mechanism.
  • the invention relates to a watch comprising at least one such movement, and / or at least one such display mechanism.
  • the same application also describes a second case of actuation mechanism by means of a first differential on the train of the first barrel and a second differential on the train of the second barrel, and at least one cam constituting an input of such a differential. Therefore, it is necessary to find and size an adequate planetary (differential) gear. Planetary gears have the advantage of achieving high transmission ratios in a small footprint.
  • the input and output shafts are an extension of each other.
  • the figure 8 shows an example of such an embodiment, with a heart cam in the right part of the figure, traversed by a curved sickle-shaped lever having an internally toothed part, with which a wheel of a first differential cooperates, in the left part in the figure, a second differential being visible in the rear right-hand part of the figure, these two differentials attacking two coaxial guns.
  • the lever of this figure does not have a return spring, because it is the elastic needle which advantageously fulfills this function.
  • the lever activates the crown, which by means of the satellites visible on the principle diagram of one of the two differentials, makes it possible to generate the necessary advance or delay.
  • This mechanism of the figure 8 performs well the function of generation of advance or delay on the guns, but remains bulky and contains many components.
  • the invention proposes to further simplify the mechanism and make it even more compact and economical to produce.
  • a small caliber such as a ladies' watch
  • the main difficulty is linked to the low torque available. It is therefore advisable to create a mechanism with the lowest possible energy consumption.
  • the invention proposes to control the satellite.
  • a probe in the satellite By setting up a probe in the satellite, and by controlling the latter with a round cam, we obtain a speed ratio equal to one between the sun wheel and the chassis carrying the satellites: the assembly then behaves like a mobile.
  • the cams shown on the figure 2 allow, thus, to obtain the trajectory of the tip of the needle of the figure 5 .

  • This flexible blade 3 can be a continuous blade, or even a blade comprising a succession of segments 5 joined two by two at the level of vertices 6, as visible on the Figures 5 and 6 .
  • This flexible blade 3 has a display index which, in an unconstrained free state of the elastic needle 1 in which both the first barrel 2 and the second barrel 4 are not subjected to any stress and are distant one on the other, is distant from the first barrel 2 and the second barrel 4, the service position of the elastic needle 1 being a constrained position where the first barrel 2 and the second barrel 4 are coaxial with one another around an output axis D.
  • the display index is advantageously, but not necessarily, constituted by a vertex 6.
  • the display mechanism 10 includes first drive means 11 for the first barrel 2 around the outlet axis D, and second drive means 13 for the second barrel 4 around the outlet axis D.
  • first barrel 2 and the second barrel 4 are not coaxial are not described here, they remain feasible for certain special displays, in particular displays which are not of revolution, such as retrograde displays or the like.
  • the first drive means 11 and the second drive means 13 are arranged to deform the flexible blade 3, by varying the angular position of the second barrel 4 relative to the angular position of the first barrel 2 around the axis of output D, and to vary the radial position of the display index relative to the output axis D.
  • the display mechanism 10 comprises a first differential 912 on the gear train of the first barrel 2, and an input of which is constituted by a first cam 92 or 820, and a second differential 914 on the gear train d drive of the second barrel 4, and an input of which is constituted by a second cam 94 or 810.
  • the first cam can be a fixed cam or a movable cam
  • the second cam can be, in the same way , a fixed cam or a mobile cam.
  • the figures 10, 12 , 14 , 16 illustrate some specific configurations.
  • the first differential 912 and the second differential 914 comprise a common planet carrier chassis or two synchronous chassis each satellite carrier, carrying or respectively carrying the satellites 82, 84, which each comprise an eccentric probe 83, 85, which is arranged to follow its respective cam 92, 820, 94, 810, depending on the variant.
  • first drive means 11 or the second drive means 13 are arranged to drive another input of an input differential, which is another input than the cam mentioned above constituting one of the inputs of the differential concerned.
  • This input differential is one of the first differential 912 and second differential 914; for example on the variant of Figures 1 and 2 , the input differential is the second differential 914.
  • This other input is constituted by a first satellite of the input differential.
  • the first satellite is mounted free in rotation on an input planet carrier frame 80 which is itself mounted free in rotation around the output axis D.
  • the sun gear of the input differential is made up, or else by a first toothing 21 worn by the first barrel 2 when the input differential is the first differential 912, or else by a second toothing 41 carried by the second barrel 4 when the input differential is the second differential 914.
  • satellite carrier chassis means a chassis capable of carrying at least one satellite, on any of its faces.
  • the other of the first differential 912 and second differential 914 is an output differential, of which another input is constituted by a second satellite of the output differential.
  • This second satellite is mounted for free rotation on the input planet carrier frame 80 as on the figure 2 , or else on an output satellite carrier chassis which is mounted to rotate freely around the output axis D and synchronous with the input satellite carrier chassis 80.
  • the output pinion of the output differential consists of a second toothing 41 worn by the second barrel 4 when the input differential is the first differential 912, or by a first toothing 21 carried by the first barrel 2 when the input differential is the second differential 914.
  • the second satellite is mounted to rotate freely on the input satellite carrier chassis 80, on the face opposite to that which carries the first satellite, as visible on the figures 2 and 3 , which show the input planet carrier frame 80 having counterbores on the upper and lower faces, and upper pivot pins 81 and lower 89.
  • the first differential 912 comprises a first satellite 82 comprising a first eccentric finger 83, which is arranged to traverse a first internal track 93 of the first cam 92 or 820, in particular a fixed cam, and is biased against the first internal track 93 by the elasticity of the elastic needle 1.
  • the second differential 914 comprises a second satellite 84 comprising a second eccentric finger 85, which is arranged to traverse a second internal track 95 of the second cam 94 or 810, in particular a fixed cam, and which is biased against the second internal track 95 by the elasticity of the elastic needle 1. It is advantageous to use the elasticity of the elastic needle 1 itself to save a return component which would be necessary to ensure the plating of each probe on its cam track.
  • the first cam, 92 or 820 in particular a fixed cam, is fixed in an indexed manner to the second cam, 94 or 810, in particular a fixed cam, with which it forms a box.

  • the first satellite projects radially, with reference to the output axis D and with respect to the first cam, 92 or 820, in particular a fixed cam, and to the second cam, 94 or 810, in particular a cam fixed ,, and is arranged to cooperate with an internally toothed ring, which comprises the display mechanism 10, for driving this at least one elastic needle 1.
  • the implementation of the invention makes it possible to obtain a wide variety of different displays, depending on the kinematics imposed on the cams and on the planet carrier chassis, or on the planet carrier chassis when there are several.
  • the first cam 92 or 820 and the second cam 94 or 810 are fixed relative to a plate or a bridge that comprises the display mechanism, and the common planet carrier 80 in the case of the figure, or both synchronous planet carrier chassis, in another variant not shown, is or are driven by a control mechanism of the display mechanism 10.
  • the figure 11 shows the ovoid trajectory T of a vertex 6 of the needle 1, associated with this mechanism.
  • first cam, 92 or 820, and the second cam, 94 or 810 are pivoting and synchronous.
  • the first cam, 92 or 820, and the second cam, 94 or 810 are pivoting and synchronous, and the common planet carrier chassis 80 illustrated, or the two synchronous chassis, each planet carrier, is or are fixed relative to a plate or a bridge that includes the display mechanism 10.
  • the figure 13 shows the linear trajectory of a vertex 6 of the needle 1, associated with this mechanism, since this elastic needle 1 here does not rotate around the exit axis D, but changes in length as a function of the shape of the cams, between a minimum radius RMIN and a maximum radius RMAX; an application consists, for example, of a linear power reserve display.
  • the first cam, 92 or 820, and the second cam, 94 or 810 are pivoting, and can be locked in a fixed position, but not permanently, because they can perform a rotational movement on demand, in particular but not limitatively one turn or an entire number of turns.

  • the figure 15 shows the square trajectory T of a vertex 6 of needle 1, associated with the mechanism of the figure 14 .

  • RMIN minimum radius
  • RMAX maximum radius
  • the figure 16 illustrates, similarly to figures 10, 12 , and 14 , another variant where one of the cams, here the second cam 810, is carried by the planet carrier frame 80: it cooperates with the second eccentric finger 85 of the second satellite 84 which is carried by the pivot pin 81 of the same satellite carrier frame 80; on the underside of this planet carrier frame 80 is similarly guided the first satellite 82, the first eccentric finger 83 of which cooperates with the first internal track 93 of the first cam 92.
