Definitions
- the present invention relates to a timepiece, including a timepiece comprising a correction mechanism indications provided by a first display member and a second display member.
- the expression "display member” means a needle, a ring, a disk, etc. which cooperates with a dial to provide an indication.
- This indication is not necessarily a temporal information. Non-limiting examples of this indication are: a calendar (annual, perpetual, day / date, etc.); moon phases, tides, regattas, AM / PM displays; a second time zone, for example a GMT time; etc.
- the displacement of a display member is generally provided by a display mobile comprising a toothing.
- This mobile can be directly connected to the display member, by driving it by a direct contact, or one or more mobile intermediaries between the mobile display and the display member ensure the training of the display unit by the display mobile.
- the display member is a needle, for example an hour hand
- its movement is ensured by a toothed wheel. hours cinematically linked to this needle.
- This hour wheel can be driven, directly or indirectly, by a mobile display.
- this ring or disc may comprise a toothing that ensures its displacement.
- the notion of display member may coincide with that of display mobile.
- These correction mechanisms generally comprise a winding stem mounted in a plate of a watch including the timepiece, this winding stem comprising a main axis.
- the winding stem is generally movable in translation in the direction of this main axis and can occupy different axial positions. It is also mobile in rotation about this axis: it can turn in a clockwise direction and also in a counterclockwise direction.
- the winding stem is movable between at least a first correction position and a winding position. In some cases, it can occupy a second correction position.
- this winding stem carries a sliding pinion (or sliding pinion), which is movable on the winding stem.
- the sliding pinion moves in a known manner on the winding stem by allowing a kinematic connection with a sliding mobile mounted freely in rotation.
- This mobile walkman is configured to cooperate directly or via a gear with the teeth of the mobiles that allow the training of the first display member or the second display member, so as to correct the information carried by these display members.
- a known example of this mobile walkman comprises a first reference, a second reference and a third reference, each reference belonging to a floor differs from the mobile walkman.
- the term “return” refers to a toothed wheel, that is to say comprising at least one tooth.
- Known references are wheels having a toothing along their entire edge, this toothing being continuous. In other words, the pitch between two teeth, that is to say the distance between two consecutive teeth, is the same for all the return.
- the teeth of the known references also have the same shape. They are generally symmetrical, that is to say they include an axis of symmetry belonging to a plane substantially perpendicular to the plane of the wheel (or in general of the mobile) to which the tooth belongs and passing through the tooth and by the center of rotation of this wheel (or mobile).
- a tooth devoid of any axis of symmetry belonging to a plane substantially perpendicular to the plane of the wheel (or in general of the mobile) to which the tooth belongs and passing through the tooth and the center of rotation of this wheel (or mobile) in this context is an asymmetric tooth.
- a tooth having a substantially triangular section is defined by a first sidewall and a second sidewall, which constitute two of the three sides of the triangle, the third side being formed by the base of the tooth. This also applies to any tooth with a point (rounded or not), even if the sidewalls have a certain curvature.
- the first flank and the second flank are the sides of the rectangle respectively of the square which define, with the head and the base of the tooth, the rectangle respectively the square. This applies even if the first flank and the second flank have some curvature.
- the height of a tooth indicates the distance between the top of a sidewall (that is to say, its farthest point of the bottom of the toothing) and the bottom (flat or round) of the teeth in correspondence of this flank.
- a tooth is symmetrical if for example, the height, the shape of the first side of the tooth and the inclination of the flank with respect to the bottom (flat or round) of the toothing in correspondence of this flank is
- a substantially sharp tooth which has a symmetry with respect to an axis belonging to a plane perpendicular to the main plane of a toothed wheel to which the tooth belongs, this plane passing through the axis of rotation of the toothed wheel and by the distal end (tip) of the tooth is an example of a symmetrical tooth.
- the first reference solutions of the state of the art is driven in a known manner by the sliding pinion so that, in the direction of rotation imposed on the first return via the winding stem, the mobile player is moved in a position where the second referral leads (directly or indirectly, ie via one or more intermediates) the first display member rotating in a first direction of rotation.
- the third return causes (directly or indirectly) a second display member.
- the mobile walkman known therefore comprises three different stages to make two corrections, which does not optimize the thickness of the timepiece.
- Another known example of the mobile walkman comprises a first reference and a second reference, each reference belonging to a floor differs from the mobile walkman.
- this mobile walkman makes it possible to make a single correction.
- the document CH684920 proposes to use a mobile walkman comprising a first return driven in known manner by the sliding pinion (reference 19 in Figure 1 of this document), and a second reference (reference 21 in Figure 1 of this document). document) which, in the sense of rotation that is imposed on the sliding pinion via the winding stem, will move either in a first position where it meshes through a gear with the toothing of a first display member (a star of days) or in a second position where it meshes directly with the toothing of a second display member (a date ring).
- An object of the present invention is to provide a timepiece free of limitations of known timepieces. Another object of the invention is to propose a part
- timepiece having a reduced thickness while allowing effective correction of the indications carried by two display members whose drive is provided by mobiles having different teeth, that is to say having different teeth, for example having a shape, a height and / or a slope of the different sides.
- This solution has the advantage over the prior art to reduce the thickness of the timepiece because it includes two references, while allowing the correction of the indication carried by two display members whose drive is provided by mobiles having different teeth: this is possible thanks to the fact that the second reference comprises at least one asymmetrical tooth.
- asymmetrical tooth indicates that the height, the shape of the first flank of this tooth and / or its inclination relative to the bottom (flat or round) of the toothing in correspondence of this first flank is significantly different from the height, shape
- first asymmetrical tooth allows effective correction of the indications carried by two display members whose drive is provided by mobile having different teeth, because a side of this tooth is adapted to lead the first. mobile and another side is adapted to drive the second mobile. It is thus possible to adapt each side of the first tooth to the type of mobile it is supposed to lead.
- the second reference according to the invention comprises a single tooth.

- each tooth of the second display mobile comprises a fifth flank and a sixth flank: in this variant, the second flank of the tooth of the second return is arranged to cooperate with this fifth flank, so as to cause the second mobile display.
- a display mobile is a date ring which generally comprises teeth having a height substantially greater than that of other moving teeth of a movement.
- the height of one of the flanks of the tooth of the second return, in particular the flank which is intended to cooperate with this ring, is thus adapted to carry out the drive of this ring.

- the force of the contact can be decomposed into two components, one tangential, that is to say substantially normal to the radius of the first display mobile, and the other radial, that is to say along the the direction of the radius of the first display mobile.
- the radial component is zero or negligible compared to that tangential, which allows excellent transmission of torque from the second reference to the first display mobile. It is also possible that the radial component of this contact becomes too large compared to that tangential, which could block and damage one or more components of the timepiece, for example and without limitation the first display mobile or the winding stem.
- the presence of the second tooth solves this problem because it allows to give a substantially tangential force to the first display mobile before the first tooth comes into contact with the first display mobile.
- the second tooth makes it possible to further improve the transmission of the torque from the second reference to the first display mobile and / or to prevent the blockage or breakage of one or more components of the timepiece .

- this group of teeth could comprise another integer number N of teeth having decreasing heights, and separated by a pitch which corresponds substantially to the pitch of the toothing of the first mobile.
- this group of teeth should not cover all the perimeter of the second return, to leave space to allow cooperation of the first tooth with the teeth of the second mobile display (the date ring for example), which has a toothing different from that of the first mobile display.

- the second flank 312 of the first tooth 310 of the second reference 30 has a height H2, visible in Figure 4, different from the height H1 of the first sidewall 311.
- the second display unit 2 is a date ring which generally comprises teeth 210 having a height substantially greater than that of the teeth of other mobile movement. The height of the flank 312 of the first tooth 310, this flank 312 being intended to cooperate with this ring 2, is thus adapted to carry out the driving of this ring 2.
