Definitions

  • the present invention relates to a timepiece device comprising a wheel set for driving a display disc as well as means allowing it to be held axially.
  • a display disc of a timepiece bears on its upper face indications intended to face a user, said indications being typically visible through an aperture of the dial covering it.
  • Such a display disc is typically driven in rotation about an axis perpendicular to the plate by a drive wheel set to which it is fixed. The maintenance in the radial position of said driving wheel set and of the display disc that it carries is ensured by this axis. Holding in the axial position, along this axis, is typically ensured, in a first direction going from top to bottom (towards the “bridge side”), directly or indirectly, by the plate or by a bridge , and in a second direction going from bottom to top (towards the "dial side”) by various means mentioned below.
  • a drive wheel carrying a display disc and pivoting around an axis can be held in position in a watch mechanism, axially, in the direction going towards the dial, by the dial itself.
  • the dial must meet a certain number of criteria. It must in particular be very flat and is therefore subject to very precise tolerances (typically between 20 ⁇ m and 40 ⁇ m) which are difficult to respect for certain surfaces or for surfaces subject to certain types of decoration such as enamelling.
  • tolerances typically between 20 ⁇ m and 40 ⁇ m
  • Another possibility for the axial retention of a drive wheel bearing a display disc is the use of a screw, passing through the display disc and the wheel bearing it and typically screwed into the plate or into a bridge.
  • This possibility has the advantage of releasing the dial from its holding function but has the disadvantage of occupying part of the upper surface of the display disc, thus limiting the space available for affixing indications thereon. Furthermore, such an arrangement is not possible when the mobile display is crossed by a shank carrying a needle.
  • the Swiss patent application CH 712 392 A2 proposes a horological device comprising a toothed wheel integral with a display disc as well as a holding plate or lever movable in translation between a first position in which a locking lug constituting one end of this lever cooperates with a holding ring integral with said display disc to hold this disc axially and guide this disc in translation display and a second position in which said display device is not held axially.
  • a screw makes it possible to lock the lever in said first position.
  • Such a device overcomes some of the aforementioned drawbacks, however, there is very little freedom as to the shape of its lever; this device is therefore difficult to adapt to the space constraints surrounding the display disc when the latter is integrated into a watch movement.
  • the axial holding of the display disc depends on the surface of the holding ring covering by the locking lug.
  • lengthening the arms of the locking beak to increase this surface involves increasing the recoil of the retaining piece by the same amount to release the display disc axially, which can pose difficulties relating to the size of the mechanism.
  • An object of the present invention is to propose a watchmaking device comprising a drive wheel bearing a display disc as well as means enabling it to be held axially within a watchmaking mechanism, remedying the aforementioned drawbacks.
  • the invention proposes for this purpose a watchmaking device comprising a frame, a drive wheel, a display disc and a holding part, said display disc bearing on its upper face indications intended to face a user. and being integral in rotation with said drive wheel located at least partly under its lower face, characterized in that said retaining piece is arranged to be able to pivot around an axis of rotation between a first and a second position fixed by relative to the frame, so that in the first of said two positions, at least a part of said piece of holding, said part being located under the display disc, or at least partly facing at least a portion of said driving wheel set in the direction of the axis of rotation of the display disc, so as to hold in the axial position the driving wheel set and the display disc in the direction going from bottom to top, and so that in the second of said two positions, no part of the said holding part is facing said drive wheel set in the direction of the axis of rotation of the display disc so as to release the axial displacement of the driving wheel set and of the display disc in the direction going
  • the device according to the invention comprises at least a first and a second fixing means making it possible to fix the holding part in the said first position, the said fixing means being arranged so that the smallest angle defined by the center of the first means of fixing, the center of rotation of the display disc, and the center of the second fixing means and whose vertex corresponds to the center of rotation of the display disc is greater than 45°, preferably greater than 90°, preferably greater at 120°, preferably even greater than 150°, ideally substantially equal to 180°.
  • Said fixing means are for example screws.
  • Said first position of the holding piece corresponds to a “locking position” of the device and said second position of the holding piece corresponds to an “unlocked position” of the device.
  • the present invention also proposes a timepiece mechanism comprising such a device and a timepiece such as a wristwatch, a pocket watch, a clock or a clock comprising such a timepiece mechanism.
  • the upper and lower faces of the display disk respectively define the top and the bottom of the device according to the invention.
  • the drive wheel according to the invention comprises at least one part intended to be driven in rotation by a watch mechanism, this part being able for example to be a wheel, preferably a toothed wheel, said drive wheel comprising said part and any element being integral with the exception of the display disc to which it is integral.
  • the mobile drive according to the invention can typically comprise a wheel secured to a barrel and/or to a support surface facilitating the connection with the display disc, it can also be a simple wheel , with barrel or without barrel, said wheel being able for example to take the form of a star.
  • the wheel in question may not include any teeth if indeed it is able to be driven in rotation.
  • the device according to the invention has the advantage of being able to hold a mobile display axially by releasing the dial from this function. This gives more freedom in the design of the dial or even the possibility of removing the dial, for example to create a “skeleton” structure.
  • such a device has the advantage of revealing the entire upper surface of the display disc available to carry indications.
  • the device according to the invention also makes it possible, by a movement guided in rotation of the holding part in a plane typically perpendicular to the axis of rotation of the display disc, to release axially the drive wheel bearing the display disc so that it is possible to remove it without requiring separation of the holding part of said timepiece device and without impacting the axial holding of other moving parts which would also be held axially other than by the dial.
  • a rotational movement of the holding part allows greater freedom in the design of said holding part than a translational movement.
  • the movement of a point of material of the holding part is different depending on its distance from its center of rotation. This means that the locking/unlocking of the mobile drive does not take place at the same rate according to the distance separating the mobile drive from the center of rotation of the holding part.
  • the further the part of the holding part intended to come into the blocking position to be placed opposite a portion of the drive wheel set is from the center of rotation of the holding part the faster the unlocking takes place.
  • the rotational movement of the holding part therefore makes it possible to better adapt to the constraints of the size surrounding the display disc when the latter is integrated into a watch movement while making it possible to increase the covering of the driving wheel and therefore to allow better axial retention of the assembly.
  • FIG. 1 represents part of a timepiece mechanism integrating a timepiece device 100 according to a particular embodiment of the invention.
  • THE figures 2 and 3 illustrate only part of this device 100.
  • the device 100 comprises a drive wheel set 2, a display disc for the day of the week 3, a plate 6, a retaining plate 10 and a fixing screw 11.
  • the mobile drive 2 is here a cannon wheel comprising a toothed wheel 2a in the form of a star with seven teeth integral with a cannon 2b.
  • the day disc 3 is driven onto the barrel 2b of the driving wheel set 2.
  • the driving wheel set 2 comprises a central hole 4 through which an axis 5 passes through a plate 6 and is free to rotate around this axis 5.
  • the axis 5 could be replaced by another barrel forming a simple hollow tube whose light would be crossed by a shank, for example carrying a needle, the shank would then be free to rotate inside the tube.
  • the shank as well as the hand would typically be rotated by the going train of said timepiece mechanism.
  • the day disc 3 has on its upper face 3a indications 9 corresponding to the days of the week. Under its other face, called the lower face 3b, is the driving wheel set 2.
  • the upper face 3a defines the upper face A of the device 100 and is typically intended to be on the "dial side” of a timepiece, ie on the side facing the user during normal use.
  • the other face, called the lower face 3b, defines the lower face B of the device 100 and is typically intended to be on the “bridge side” of a timepiece.
  • the drive wheel set 2 is kinematically connected to the going train and intended to be driven in rotation at a rate of one revolution per week, and to drive in rotation the day disc 3 to which it is attached.
  • the drive wheel 2 is held in a radial position within the watchmaking device by the axis 5 constituting a physical axis around which it pivots, the virtual or imaginary pivot axis of the drive wheel 2 and of the disc 3 being designated by A2. It is held in the axial position, in the direction of the lower face B , that is to say in the direction going from top to bottom, typically directly, by the plate 6 and in the direction of the upper face A , that is i.e. in the direction going from bottom to top, by the retaining plate 10 of the device 100.
  • the screw 11 of the device 100 passes through a circular hole 12 of the retaining plate 10 and is screwed into a thread 13 driven into the plate 6, said plate 6 constituting a frame of the device 100.
  • the screw 11 is located outside the part of the plate 6 which is opposite the display disc 2 (in the direction of the axis A2) in order to be accessible, that is to say screwable and unscrewable, once the display disc 3 the retaining plate 10 in place.
  • the retaining plate 10 of the device 100 comprises a recess 15 also intended to be crossed by a screw 16 screwed into a thread of the plate 6.
  • the screw 16 is located outside of the part of the plate 6 which is opposite the display disc 3 (in the direction of the axis A2) in order to be accessible, that is to say screwable and unscrewable, once the disc is display 3 and the holding plate 10 in place.
  • FIG 1 illustrates the holding plate 10 in the blocking position, that is to say in the position in which it blocks axially, in the direction from bottom to top, the driving wheel set 2.
  • the screw 11 at least is completely screwed into the thread 13 and immobilizes the retaining plate 10 by tightening it against the plate 6, that is to say that it makes it integral with plate 6.
  • the screw 16 is also completely screwed in the locking position.
  • a second fixing screw such as screw 16 is not essential.
  • a screw reinforces the immobilization of the holding plate 10 and makes the whole of the device 100 more resistant to shocks.
  • having at least two fixing means for the holding plate 10 arranged on either side of the display disc 3, preferably diametrically opposed with respect to the center of rotation of this disk 3, has the advantage of limiting the bending of the holding plate, in particular in its part contributing to the axial holding of the display disk 3, and thus of avoiding the movement of the toothed wheel 2a in the up/down direction.
  • the smallest angle A1A20 is approximately equal to 165°. This angle could be different but preferably greater than 45°, ideally substantially equal to 180°.
  • the retaining plate 10 is positioned between the lower face 3b of the day disc 3 and the lower face of the driving wheel set 2. It typically extends in a plane parallel to the plane in which extends the day disk 3. At least one part (arm 1) of said holding plate 10, said part being located under display disk 3, is directly opposite a portion of drive wheel set 2, in the direction of the (virtual) axis A2 of rotation of the display disk 3. Said portion of the driving wheel set 2 here corresponds to a portion of the toothed wheel 2a. There cooperation between the holding plate 10 and said portion of the toothed wheel 2a allows the axial holding of the driving wheel set 2 and of the day disc 3 in the direction going from bottom to top.
  • the assembly comprising the retaining plate 10 and the screw 11 is located below the plane defined by the upper face 3a of the display disk 3. Thus, it does not create any thickening of the mechanism. Moreover, in the case where the device 100 is integrated within a timepiece comprising a dial, the assembly comprising the retaining plate 10 and the screw 11 does not create a space between the display disc and said dial.
  • said part of the retaining plate 10 is directly opposite said portion of the toothed wheel 2a, in the direction of the (virtual) axis A2 of rotation of the display disc 3. It could also be imagined that these parts and portion face each other indirectly.
  • the device 100 authorizes the guided movement in rotation of the retaining plate 10 with respect to the plate 6.
  • the screw 16 must also be unscrewed.
  • the edges of the circular hole 12 are free to pivot against the external diameter of the thread 13 in which the screw 11 is screwed, the thread 13 / hole 12 assembly constituting a guide system for the plate of maintaining 10 in rotation around a (virtual) axis of rotation A1 coinciding with the axis of the screw 11.
  • This configuration corresponds to the so-called unlocked position.
  • the pivoting of the retaining plate 10 makes it possible to radially move the parts of the retaining plate 10 and of the drive wheel set 2 which are opposite each other in the locking position, from so that they are no longer so, in order to release the axial holding of the driving wheel set 2 in the direction going from bottom to top.
  • the device 100 is typically mounted within a watch mechanism comprising a jumper 17 to position the toothed wheel 2a with precision so that the display disc 3 (not shown in this figure), secured to the star is positioned correctly .
  • the retaining plate 10 can advantageously carry a pin 18 arranged to lift the jumper 17 against the action of its return spring 19 when the retaining plate 10 moves from the locking position to the unlocking position.
  • the pin 18 is positioned away from the pivot axis A1 so as to have a sufficient distance to travel or radial displacement to allow the jumper to be lifted. This pin 18 does not intervene in the normal operation of the device 100.
  • the mechanism in which the device 100 is integrated could comprise one or more other organs, for example another jumper, arranged to cooperate with one or more part(s) of the holding plate 10 using a set of distances to be traveled specific to the function(s) of the said other organ(s).
  • the retaining plate 10 shown in figures 1 to 3 can move, in a plane substantially identical to the plane in which it is in the blocking position (possibly slightly above), in rotation around the body of the screw 11 (in the direction indicated by the arrow R at the figures 2 and 3 ).
  • the retaining plate 10 and the screw 11 could be replaced respectively by any other retaining piece and by any other suitable fixing means.
  • the drive wheel has a different shape and is made integral in rotation with the display disc by means other than that mentioned above.
  • said drive wheel can typically comprise a wheel secured to a support surface on which the display disc would be glued, driven in or brazed.
  • the drive wheel set and the display disc can also be made integral in rotation by any other suitable means.
  • the display disc of the device according to the invention may be different from a day disc, it may, for example, typically be a moon disc, a disc indicating the date of the days, the current month, day and night, hours, minutes or seconds (for a trailing or jumping indication), the signs of the zodiac or any other indication of a calendar of any culture, the reserve of running, leap years, or any other display disc.
  • the drive wheel bearing the display disc and driving it in rotation typically comprises a toothed wheel but it can also be another type of drive element, for example a non-toothed wheel able to be rotated by friction.
  • the holding part can take other forms than those illustrated in the figures. It can typically take any form allowing it to perform its function.
  • the retaining part could be held in position by any suitable means other than a screw, for example by clamping or pinching against a part, including against a part belonging to the frame.
  • the expression display disk is of course not limited to a disk of circular shape.
  • the axis of rotation of the driving wheel set is substantially perpendicular to the plate and the holding part extends in a plane substantially parallel to the plate.
  • the axis of rotation of the drive wheel set it is quite possible for the axis of rotation of the drive wheel set to be inclined with respect to the plate and for the retaining piece to extend in a plane not parallel to the plate.
