  • the invention relates to the field of watch mechanisms, and more particularly to the protection of certain mechanisms against excessive torque input, in particular energy recharging mechanisms such as winding mechanisms, or correction and/or display mechanisms, in particular calendar mechanisms or the like.
  • Some watch mechanisms are designed to store and restore significant quantities of energy, however their dimensioning is limited by that of the case of the timepiece concerned, and it is not possible to apply high safety coefficients to them to protect them against excessive torque applied to them.
  • the significant bulk of the mechanisms Known torque limiters restrict the integration of complications into the timepiece.
  • the user does not have the possibility of knowing whether he has correctly and safely carried out a complete manipulation, in particular for winding a mechanism.
  • the document CH703483A2 on behalf of SEIKO discloses a wheel with a torque limiting mechanism comprising an engagement arm portion extending from a proximal end portion to a distal end portion equipped with an engagement projection, which is elastically engaged in a pressure-engaged portion.
  • the projection is detached from the engaged portion to rotate the crown wheels when a torque exceeding a threshold value is exerted.
  • a force directed from the proximal end portion to the distal end portion is applied to the projection when a manual winding torque is applied to the mechanism and adapted to separate the projection from the engaged portion.

  • the invention relates to an internal torque limiting mechanism for a clock movement, according to claim 1
  • the invention also relates to a barrel arming device comprising such a torque limiting mechanism.
  • the invention also relates to a clockwork movement comprising, between an input mechanism and an output mechanism, such a torque limiting mechanism.
  • the invention also relates to a timepiece, in particular a watch, comprising at least one such torque limiting mechanism, and/or at least one such movement.
  • the invention relates to a torque limiter mechanism 100 for a watch.
  • This mechanism 100 comprises a first mobile 1, which comprises a first rim 10 and is arranged to pivot about a first axis of rotation D1 relative to a structure 4 or a plate or a bridge.
  • This first mobile 1 comprises at least one first elastic arm 31, which, in the free state of the first mobile 1, projects in the direction of the first axis of rotation D1 relative to the first felloe 10. More particularly and non-limitingly, this first elastic arm 31 is movable in a first cutout 41 of the first mobile 1.
  • the mechanism 100 comprises at least one second mobile 2, which comprises a second rim 20 and arranged to pivot relative to the structure 4 around a second axis of rotation D2, parallel or coincident with the first axis of rotation D1, at least partially overlapping the first.
  • the mechanism 100 comprises a travel limiter 5, which is fixed to the structure 4, and which is arranged to hold the second mobile 2 on the first mobile 1 for their cooperation in friction support in certain relative angular positions.
  • the invention is here more particularly described in the simplified case where the mechanism 100 only comprises the first mobile 1 and the second mobile 2, the person skilled in the art will be able to extrapolate this to a greater number of mobiles, for a mechanism comprising more than one input and one output.
  • the invention proposes to vary the friction force between the first mobile 1 and the second mobile 2.
  • the second mobile 2 and/or the travel limiter 5 and/or the structure 4 comprises at least one relief forming a ramp, and which projects in a direction parallel to or coincident with that of the first axis of rotation D1.
  • This relief is arranged to, in certain relative angular positions of the component carrying this relief relative to the first mobile 1, cooperate in frictional support with at least one first elastic arm 31 of said first mobile 1, and, in other relative angular positions, allow a relative travel without friction between the first mobile 1 and the component carrying this relief.
  • the mechanism constitutes a simple ratchet, arranged to vary the axial position of the first elastic arm of the first mobile 1, or to vary the axial position of the entire first mobile 1 and thus vary the friction force applied to the second mobile 2.
  • the invention relates more particularly to the case where the second mobile 2 comprises at least one second arm 32 forming a ramp and which, in the free state of the second mobile 2, projects in the direction of the second axis of rotation D2 relative to the second rim 20.
  • this second arm 32 is a second elastic arm 32. More particularly still, this second arm 32 is a second elastic arm 32 movable in a second cutout 42.
  • first mobile 1 and the second mobile 2 When only the first mobile 1 and the second mobile 2 have reliefs projecting relative to their respective rim, they are mounted head to tail, with each first elastic arm 31 projecting towards the second mobile 2, and with each second arm 32 projecting towards the first mobile 1.
  • the second axis of rotation D2 is distant from the first axis of rotation D1.
  • the second axis of rotation D2 is merged with the first axis of rotation D1.
  • each second arm 32 is arranged to cooperate successively, during a relative rotation of the second mobile 2 with respect to the first mobile 1, cyclically with the first serge 10, a first elastic arm 31, and a first cutout 41 before returning in cooperation with the first serge 10.
  • first mobile 1 and the second mobile 2 are arranged, if they are coaxial, to rotate in the same direction: either they both rotate in the same direction, or one rotates and the other is blocked. These mobiles can, in other applications where they are not coaxial, rotate in opposite directions to each other.
  • Each first elastic arm 31 of the first mobile defines a first ramp, which begins at a joint 310 with the first felloe 10, and rises to a first peak. More particularly and as visible in the figures, this first elastic arm 31 is a cantilever arm, and the peak coincides with the distal end of this first arm 31, the edge of which defines a first front surface 311.
  • any relief of an opposing mobile, in particular the second mobile 2 during a rotation always in the same direction of each mobile, climbs this first ramp, then falls after passing the peak; depending on the configuration, this relief falls on the first felloe 10, or in the first cutout 41. This jump corresponds to the disengagement of the mechanism.
  • the first elastic arm 31 comprises an ascending ramp from the first felloe 10 to the first apex, then a descending ramp from the first apex to the first felloe 10.
  • the relief of the second mobile 2 can be formed in different ways, the figures represent this relief in the form of a second elastic arm 32 similar to the first elastic arm 31 of the first mobile 1, this configuration is advantageous because it makes it possible to use, for the first mobile 1 and the second mobile 2, identical components, at least at the level of these reliefs cooperating with each other; of course, depending on the application, the first mobile 1 and the second mobile 2 can comprise different teeth, depending on the components of the movement with which they cooperate.
  • each first elastic arm 31 is arranged to cooperate successively, during a relative rotation of the second mobile 2 relative to the first mobile 1, with the second felloe 20, a second arm 32, and a second cutout 42 which comprises the second mobile 2, before returning in cooperation with the second serge 20.
  • the arrangement with a first front surface 311, and a second similar front surface 312 for the second elastic arm allows, in a particular direction of rotation, the cooperation in abutment of one with the other, and the driving in rotation by simple support, without friction, of one mobile by the other, whereas, in the opposite direction of rotation, the elastic arms cooperate progressively until a release position where one of the mobiles is no longer driven by the other.
  • each first elastic arm 31 is a substantially annular sector which extends substantially concentrically relative to the first axis of rotation D1. Its radial section may be constant, or progressive or degressive, so as to obtain variable friction according to the relative angle between the opposing mobiles.
  • the upper surface of the first elastic arm 31 extends, radially relative to the first axis of rotation D1, perpendicular thereto. In a variant not illustrated, this first elastic arm 31 may also be warped and sloping.
  • Each second elastic arm 32 may be formed in a similar manner. And in particular, more particularly, each second elastic arm 32 extends substantially concentrically relative to the second axis of rotation D2.
  • At least one first elastic arm 31 and/or at least one second arm 32 extends substantially radially relative to the axis of rotation of the mobile which carries it.
  • the mechanism 100 comprises, in at least partial superposition in a direction parallel to the axis of rotation of each of them, more than two mobiles arranged to cooperate two by two in friction support, and all mounted captive between the structure 4 and the travel limiter 5, and at least one intermediate mobile between the end mobiles comprises at least one elastic arm projecting on each side of its rim, in its axial direction: this is the case of the second mobile 2 of the figure 18 , which cooperates, on the upper side of the second rim 20, with the first mobile 1, and, on the lower side of the second rim 20, with the relief 39 projecting from the third rim 90 of a third mobile 9 resting on the structure 4.
  • the invention also relates to a barrel winding device 200, comprising a control member 201 which is arranged to be operated by a user, such as a control rod, a pusher, a target, a bezel, or the like, and to drive an input pinion 202 meshing with the first mobile 1 or the second mobile 2 of such a torque limiter mechanism 100, which this device 200 comprises.
  • the other mobile of this mechanism 100, the second mobile 2 or respectively the first mobile 1 is arranged to drive a ratchet 203 of a motor or striking barrel, the whole being assembled on the structure 4 which is, in this particular case, a barrel bridge.
  • the travel limiter 5 is advantageously a screw fixed on this structure, which facilitates the assembly of the entire mechanism 100 and allows disassembly.
  • the usual crown wheel is split into two boards, constituting the first mobile 1 and the second mobile 2, and advantageously in a very economical embodiment, first 31 and second 32 elastic arms are cut and folded in each of them. These boards are then mounted head to tail in place of the crown wheel.
  • the first mobile 1 meshes with a winding pinion 202
  • the second mobile 2 meshes with the barrel ratchet 203.
  • the first mobile 1 and the second mobile 2 are secured by means of the elastic arms 31 and 32, which transmit a torque by friction. If the torque applied to the winding pinion 202 is too great, the elastic arms 31 and 32 deform and slide against each other, until the system disengages. When disengaging, the jump made by the elastic arms 31 and 32 during the unlatching produces a characteristic noise which informs the user that the barrel is fully reloaded.
  • each mobile 1, 2 has three elastic arms 31, 32. After disengagement, the first mobile 1 makes a third of a turn.
  • the clearance between the rims of the two mobiles is between 0.06 and 0.10 mm, and the axial elastic travel of each arm is half the value of this clearance.
  • the invention also relates to a clockwork movement 500 comprising, between an input mechanism 300 and an output mechanism 400, such a torque limiter mechanism 100.
  • the input mechanism 300 is a calendar or date mechanism
  • the output mechanism 400 is a month, or day of the week, or date display mechanism.
  • the torque limiter 100 is arranged to control, during any jump of an arm of a mobile 1 or 2 of the torque limiter 100, the advancement of one step of the display concerned.
  • the control of the correction of the day of the week display is a cyclic control for which the device according to the invention is well suited. In the same way, a clear adjustment of date correction can be obtained.
  • the invention is easily adaptable to any semi-instantaneous or trailing display: months, days, time zones, hours, or others.
  • the invention also makes it possible to produce an inverter for mono- or bidirectional winding: the first mobile 1 meshes with an automatic winding oscillating weight, and the second mobile 2 meshes with the winding gear train.
  • the system clicks and the second mobile 2 does not rotate.
  • the first mobile 1 rotates in the counterclockwise direction, it drives the second mobile 2 through the distal ends 311, 321, of the elastic arms 31 and 32.
  • the movement 500 comprises an automatic winding oscillating weight and an automatic winding gear train
  • a torque limiter 100 comprising elastic arms 31, 32, constitutes an inverter for mono- or bidirectional winding, the first mobile 1 meshing with the automatic winding oscillating weight, and the second mobile 2 meshing with the winding gear train, such that, when the first mobile 1 rotates in the clockwise direction, or respectively counterclockwise, the system unlatches and the second mobile 2 does not rotate, and when the first mobile 1 rotates in the counterclockwise direction, or respectively clockwise, it drives the second mobile 2 through distal ends 311, 321, which the arms respectively comprise elastics 31, 32.
  • the invention also makes it possible to produce a blocker, for example to prevent a barrel from discharging.
  • the ratchet can be arranged with elastic arms, and the barrel bridge with notches, so that the ends of the arms fall into the notches.
  • the movement 500 comprises at least one barrel and one ratchet arranged on a barrel bridge, and such a torque limiter 100 constitutes a blocker, to prevent a barrel from discharging, the ratchet constituting one of the mobiles 1, 2, and comprising arms elastic, and the barrel bridge constituting a structure 4 and comprising notches, so that the ends of the arms fall into the notches.
  • the input mechanism 300 is a minute repeater trigger mechanism
  • the output mechanism 400 is a minute repeater mechanism.
  • the torque limiter 100 is then arranged to control, during any jump of an arm of a mobile 1 or 2 of the torque limiter 100, the tilting of an isolator, which the minute repeater mechanism comprises, to prohibit the control of another repeater during the execution of a repeater strike.
  • the invention also relates to a timepiece 1000 comprising at least one such torque limiter mechanism 100, and/or at least one such movement 500. More particularly, this timepiece 1000 is a watch.
  • the proposed mechanism is very simple, because it does not require any elastic return means other than those carried by the first mobile 1, and preferably the second mobile 2.
  • the coaxial arrangement of the mobiles is particularly advantageous, because the forces exerted on the mobiles are symmetrical, and the transmissible force is maximum.
  • the arrangement in the clockwork movement involves offsetting the first 1 and the second 2 mobiles, it is advantageous to increase the number of elastic arms to avoid blind spots.
  • the production of mobiles can come, very economically, from stamping, the mobiles can be identical, and possibly differ only by their teeth.
  • the invention allows the user to ensure the proper completion of the function he is performing, winding, display correction, triggering, and ensures the protection of the components of the mechanism concerned against any excessive torque.
