Definitions

  • the invention relates to a device for displaying a temporal information with the aid of an indicator member for a timepiece.
  • the display In some display devices, called “retrograde", the display is non-circular. Instead of performing a complete revolution, the indicator organ travels from a starting point A to an arrival point B in front of a graduation representing a quantity related to time. Once the path from A to B is achieved, the indicator organ returns back to point A instantaneously.
  • This type of display can be used for any type of size related to time, such as seconds, minutes, hours, days, weekdays or moon phases.
  • a retrograde display device generally comprises a cam in the form of spiral or spiral, whose profile has an abrupt flank.
  • a lever is supported against the cam via a probe.
  • a return spring ensures the support of the lever against the cam.
  • the lever is provided with a rake, or toothed portion, adapted to mesh and drive a drive gear of the indicator member.
  • the rotation of the cam in a first direction corresponding to the chronological direction, or hourly causes the driving of the indicator member from its starting position A, in which the probe is in a low position down the side of the cam, to its arrival position B, in which the probe is in the up position at the top of the side of the cam.
  • the cam continues to rotate.
  • the probe then moves from its high position to its low position instantaneously, causing the indicator member to return to the starting position A.
  • the document EP1918792 discloses a timepiece provided with a conventional retrograde display device having a spiral-shaped cam and a retrograde display lever in contact with the cam profile via a feeler.
  • the display lever controls an indicator hand of a time size.
  • a disengagement device is added to the display device.
  • the disengagement device allows to move the probe from the retrograde display lever of the path of the cam.
  • the indicator needle is in a predetermined position and indicates no value of the time value.
  • the disengagement device thus makes it possible at any time to perform a bidirectional correction of the display of the time value.
  • the correction made is not visible to the user, which may lead to adjustment errors of the timepiece.
  • the disengaging device requires a large number of components that are added to the conventional mechanism.
  • the object of the invention is to provide a device that overcomes the drawbacks mentioned above and improves the devices known from the prior art.
  • the invention proposes a simple, reliable and robust device allowing a rearward correction of a retrograde system.
  • the invention relates to a display device according to claim 1.
  • the invention thus originates from a problem of retrograde display device.
  • the applicant intends not to limit the scope of his application to this particular example of application, but to extend it to any type of display device comprising a cam with at least one sidewall and a control probe intended to raise this sidewall. .
  • the cam flank When raising the flank by the probe, the cam flank exerts on the probe a force of action.
  • This action force has the effect of acting on the probe so as to move relative to the lever, against the return action of the second elastic means, and thus to avoid damaging the mechanism.
  • the invention provides for interposing second elastic means between the feeler and the lever so as to allow a displacement relative of the probe relative to the lever during the ascent of the sidewall.
  • These second elastic means are of course distinct from the first elastic means which are arranged to bias the lever so as to bear against the cam via the probe. During the relative movement of the probe relative to the lever, the probe approaches the lever and thus retracts against the return action of the second elastic means.
  • the action force exerted by the sidewall of the cam on the probe during the passage of the sidewall in the second direction of movement of the cam acts to cause immobilization of the lever.
  • the action force acts on the lever to cause a pivoting effect thereof against a stop.
  • the lever being adapted to pivot about a pivot point, the action force passes substantially through said pivot point of the lever.
  • the drive lever comprising a drive arm of the indicator member, an angle of action, formed by the action force of the cam on the probe and the segment connecting the point of contact of the probe and the cam flank and the pivot point of the lever is located in the half-plane defined by the line containing said segment and not containing the drive arm of the lever.
  • the line containing the point of contact between the probe and the cam and the pivot point of the lever defines two half-planes, one containing the lever drive arm, the other not containing said arm.
  • the positioning of the angle of action in the half-plane not containing the lever arm has the effect of ensuring a force tending to pivot the lever arm in the correct direction to immobilize it against the stop.
  • said angle of action is between 0 and 180 °.
  • the invention thus uses, in a clever way, the stop immobilizing the lever at the end of descent of the sidewall to also immobilize the lever during the ascent of the sidewall.
  • said stop is arranged to immobilize the lever, during the displacement of the cam in the first direction, when the probe reaches the bottom of the sidewall.
  • the probe head is thus shaped to ensure continuous contact between the probe and the cam flank, during the entire movement of the probe along the cam flank, during the ascent of the cam flank.
  • the geometry of the probe is advantageously adapted so that there is no contact between the probe tip and the sidewall when the probe passes from the top of the cam flank to the bottom of the cam flank.
  • the probe in another embodiment, includes a head flange shaped to provide continuous contact between the probe flank and the upper end of the cam flank (i.e., the end at the cam portion of larger radius), during the ascent of the cam flank by the probe.
  • the probe is pivotally mounted on the lever.
  • the probe can rotate relative to the lever without arching.
  • an angle formed by the normal to the cam in contact between the feeler and the cam flank and the half-line originating from said contact and passing through the pivot point of the probe is greater than the angle formed by the normal to the contact between the probe and the cam flank and the reaction force exerted by the probe on the sidewall.
  • the displacement of the cam in the first direction causes a prestressing of the second resilient means, which is compensated by a shaped cam profile to ensure an accurate display of the time information.
  • the second resilient means comprise a flexible blade.
  • the lever, the second elastic means and the probe are made in one piece.
  • the lever is secured to a toothed portion adapted to cooperate with the toothing of a drive pinion of the indicator member.
  • the toothed part may comprise teeth to catch play.
  • the teeth clearance play allows to minimize display errors. It still helps to limit shocks and mitigate the effects of inertia when the time indication element suddenly returns to its initial position.
  • the lever can be manufactured with one of the materials of the group comprising Ni, NiP and Si.
  • the invention also relates to a watch movement comprising a display device defined above.
  • the invention also relates to a timepiece integrating the display device defined above or the watch movement defined above.
  • the timepiece may comprise a basic movement and a display device defined above, the cam of the display device being driven by the base movement.
  • a first embodiment of the display device according to the invention is represented on the figure 1 showing an embodiment of a timepiece 300 according to the invention.
  • the timepiece comprises a watch movement 200.
  • the watch movement comprises the display device 100.
  • This display device is intended to be integrated into a watch movement of a timepiece.

  • the needle 1 is intended to make an instant return trip from the "24h” position to the "0h” position at midnight.
  • the invention could of course be applied to any type of magnitude related to time (seconds, minutes, calendars, days of weeks, moon phases, etc.), to a retrograde display represented on any angular arc and to a non-retrograde display, as will be explained in more detail at the end of the description.

  • the cam 2 has a flank 23 connecting the cam portion of smaller radius and the cam portion of larger radius. In normal operation (that is to say during a time display phase), the flank 23 has the role of ensuring the return to the initial position "0h" of the indicator hand 1, once the final position "24h” reached.

  • Figure 4B represents an enlargement of the cam 2 and the probe head 31 in the "0h” position.
  • the lever 4 pivots in the trigonometric direction until it bears and stops against the stop 7. The pivoting of the lever 4 causes a return back snapshot of the needle 1 from the "24h” position to the "0h” position, by rotation in the antitrigonometric direction.
  • the return spring 5 is dimensioned so as to be as rigid as possible during the rotation of the cam 2 in the forward direction (trigonometric direction in the particular example described). However, this rigidity is limited by the stresses within the material and the allowable torque to the cam 2 during a correction of the time in reverse. Indeed, it is not necessary that the rigidity of the spring 5 is too important, because it would result in significant efforts to allow the passage of the flank 23. As a result, during the rotation of the cam 2 in the direction of travel before, in normal operation, the return spring 5 undergoes a prestressing and is slightly deformed under the action of the cam 2 on the probe 3. This preload and this deformation depend on the action exerted by the spring 6 recalling the lever to the stop 7.
  • this action itself depends on the position of the lever relative to the stop.
  • This deformation induces a time shift in the display of the needle 1 relative to the display of a needle connected to a mechanism comprising a probe mounted rigidly on a lever.
  • This time difference is quantifiable and corresponds to a given duration, for example 1h. It is compensated by an adaptation of the cam profile 24.
  • the cam profile 24 is adapted, modified with respect to a cam profile, said "initial”, 25 operating with a similar mechanism (feeler, spring and lever) that would be perfectly rigid.

  • the cam 2 is rotated in a second direction, called "reverse", anti-trigonometric.
  • the needle 1 moves from the "24h” position to the "0h” position.
  • the cam follower 31 is positioned at the bottom of the cam flank 23 and the lever 4 bears against the stop 7.
  • the immobilization of the lever 4 during the ascent of the flank 23 allows immobilization of the needle 1 and prevents any erroneous indication of the needle 1 during the ascent of the flank 23.
  • the needle 1 is instantaneously in a synchronized display position with the position of the main hands 30 and 40 of the hours and minutes, as shown in FIGS. Figures 6A and 6B .
  • the stop 7 serves, during normal operation, to immobilize the lever 4 at the end of descent of the sidewall 23 and thus to immobilize the needle in position "0h” just after midnight, after its return “retrograde” from the position "24h” .
  • the stop 7 also serves to stably immobilize the lever 4 and thus immobilize the needle 1 in the "0h” position. Thanks to this, the needle 1 is perfectly stable during the ascent of the flank 23.
  • FIGS 7A to 7C represent the force vector F action of the cam flank 23 on the probe head 31 and the force vector F the feeler tip 312 is reacted on the flank 23 during the raising of the flank 23 by the probe head 31.

  • the pivot point 32 is thus determined so that at the moment when the tip 312 reaches the top of the cam 2, the angle ⁇ is greater than the angle Atan ( ⁇ ) and thus allows the probe 3 to pivot relative to the lever 4. It will be noted, with reference to the Figure 7B , that when the probe tip 312 reaches the top of the cam 2, the compression of the return spring 5 is maximum.
  • the pivot point 44 of the lever 4 is defined in such a way that the action force F immobilizes the lever 4 or causes a pivoting of the lever 4, here in the counterclockwise direction, against the stop 7, which has the effect of to immobilize the lever 4.
