Description

FIELD OF THE INVENTION [0001] The invention relates to a sequencer mechanism comprising a first rotation-driven locking device comprising a peripheral surface that is uniformly held in its geometry or in a magnetization of uniform polarity, arranged to keep a mobile stationary antagonist receptor.

The invention further relates to a clockwork mechanism comprising at least one such sequencer mechanism.

The invention also relates to a watch comprising at least one such clock mechanism and / or at least one such sequencer mechanism.

The invention relates to the field of clockwork mechanisms with torque or movement transmission. BACKGROUND OF THE INVENTION [0005] The invention relates to an alternative to the Maltese Cross system whose function is to transform a continuous rotation into a jerky rotation. This is for example to rotate a passing wheel of a step (often a quarter of a turn) to the passage of an irregularity (complementary shape) on a driving mobile which is subjected to a continuous rotation. This system is for example used in watchmaking to stop movement, or in perpetual calendars to rotate a quarter turn a cam leap years at the passage of each year.

Such a system is very practical because it consumes almost no energy in passing. Indeed, it does not require a jumper to hold the wheel of passage, because its rotation is directly blocked by the mobile driver in case of shock. This is valid for passing wheels not being subjected to a torque, but is not valid in the case where the wheel is subjected to a torque, permanent or not. Indeed, the friction generated at the interface between the passage wheel and the driving carrier represents a permanent consumption and proportional to the forces present on the latter. SUMMARY OF THE INVENTION [0007] The present invention consists in adapting this transformation principle, in cases where the wheel is subjected to a non-negligible torque, and where it is necessary to limit the brake generated on the driving mobile as well as possible.

For this purpose, the invention relates to a sequencer mechanism according to claim 1.

The invention also relates to a clockwork mechanism comprising at least one such sequencer mechanism.

The invention also relates to a watch comprising at least one such clock mechanism and / or at least one such sequencer mechanism.

Of course, one can substitute a smooth track combined with idle rollers, a toothing combined with idle gears, or the like, without departing from the present invention. Crazy rollers are advantageous by their slightest friction.

The electrostatic variant of the invention is not described here in detail, the watchmaker will transpose the teachings of the magnetic alternative described below to an electrostatic variant, operating in the same way.

These second stop elements 21 cooperate in pairs with the holding surface 11, on either side of a plane passing through the centers of the mobile blocker 1 and the mobile receiver 2, to keep the mobile stationary in motion. rotation during the holding stroke.

The first mobile blocker 1 further comprises at least one driving surface 12, comprising, or an irregular terrain when the peripheral holding surface 11 is regular in its geometry, or respectively a contrary magnetization when the peripheral surface of holding 11 is regular in a magnetization of uniform polarity.

And this drive surface 12 is arranged to jump the mobile receiver 2 in a drive stroke of the first mobile blocker 1 between two holding strokes. It is understood that, with respect to an interaction zone of the mobile receiver 2, the rotation of the first mobile blocker 1 is an alternation of holding strokes during which the mobile receiver 2 is stationary, and of training races during which the mobile receiver 2 performs a rotation.

More particularly, the first blocking mobile 1 is subjected to a motor torque which causes it to rotate about the first pivot axis D1. The sequencer mechanism 100 is arranged to transform the rotation of the first mobile blocker 1 into a jerk rotation of the second mobile receiver 2 which is arranged in the immediate vicinity of the first mobile blocker 1, and pivots around the second pivot axis D2, of which the position in space is fixed relative to that of the first pivot axis D1.

In this stop position, the two second stop elements 21, which cooperate with this first holding surface 11, can have a support on either side of a main plane P passing through the first pivot axis D1 and by the intersection of the second pivot axis D2 with the median plane PM.

More particularly, it is the two elements of the pair that are in contact with the first holding surface 11.

These second stop elements 21 are further arranged to cooperate each by mechanical or magnetic drive, as the case may be, with such a first driving surface 12 arriving at its vicinity, to allow the second receiving mobile 2 to pivot. the effect of the drive by the first mobile blocker 1 or under the effect of a torque which is subjected to the second mobile receiver 2, in a drive stroke of the first mobile blocker 1. In the mechanical alternative, the second stop elements 21 comprise idler rollers or the like, which are arranged to roll on a substantially cylindrical track constituting the first holding surface 11, and which are still arranged to penetrate into at least one notch constituting a first driving surface 12. This notch is arranged to allow or generate the rotation of the second mobile receiver 2. In the magnetic alternative e, the second stop elements 21 comprise receiving magnets, which are arranged in repulsion with a magnetized track of first polarity constituting the first holding surface 11, and which are still arranged to cooperate in attraction with at least one second track reverse polarity at the first polarity constituting such a first driving surface 12.

More particularly, the first blocking mobile 1 is subjected to a motor torque which gives it a continuous rotation about the first pivot axis D1.

In a first embodiment, as shown in FIGS. 1 to 5, and 11, the second mobile receiver 2 is subjected to a motor torque with respect to the second pivot axis D2, in agreement with the driving torque applied to the first mobile blocker 1.

In another embodiment, as shown in FIGS. 6 to 10, the second mobile receiver 2 is not subject to any engine torque relative to the second pivot axis D2. This second mobile receiver 2 can, again, be subjected to a resistive torque, that is to say in opposition to the driving torque applied to the first mobile blocker 1.

In a particular variant, corresponding to the embodiments illustrated in the figures, the second stop elements 21 are all identical.

More particularly, each first holding surface 11 is arranged to drive at least a second stop element 21 in a step of the second mobile receiver 2, by mechanical contact or by a magnetic force, over an angular drive range. restricted to the first mobile blocker 1, and the first driving surface 12 then comprises two elementary surfaces 13, 14, which are arranged to cooperate with two such second different stop elements 21, to allow the second mobile receiver 2 to pivot, each on a part of the step.

In a particular variant not illustrated, the first mobile blocker 1 comprises at least two levels defining together a first gap in which or in the immediate vicinity of which is movable the periphery of the second mobile receiver 2.

In a particular variant similar and illustrated in FIGS. 14 to 16, the second mobile receiver 2 comprises at least two levels 2A and 2B, together defining a second gap in which or in the immediate vicinity of which is movable the periphery of the first mobile blocker 1.

In a particular variant of the mechanical alternative, the second stop elements 21 are arranged to cooperate each by mechanical drive with a first drive surface 12, and the second mobile receiver 2 comprises a plurality of such rollers of which the pivot axes are equidistant from the second pivot axis D2. These pivot axes can, moreover, be inclined regularly with respect to the second pivot axis D2.

More particularly, and as illustrated by FIGS. 1 to 11, these rollers are equidistant.

In the variant where the second mobile receiver 2 is not subjected to a driving torque, a particular arrangement is necessary so that it can rotate under the action of the first mobile blocker 1. More particularly, for this purpose, at least one first driving surface 12 comprises two elementary surfaces 13 and 14 in the form of notches arranged to receive the rollers, separated by a projecting finger which is arranged to be introduced between two consecutive rollers. This finger 15 is arranged to bear on one of the rollers, at a contact surface which is closer to the second pivot axis D2 than the pivot axis of the roller concerned, as shown in FIGS. 7 to 9, for driving in rotation the second mobile receiver 2 when it is not driven or is subjected to a resistant torque.

In the magnetic alternative, the second stop elements 21 are arranged to cooperate each by magnetic drive with a first driving surface 12, and the second mobile receiver 2 comprises a plurality of second magnets constituting the receiving magnets and oriented according to the first polarity to the periphery of the first blocking mobile 1. These second magnets are equidistant from the second pivot axis D2; by this is meant that the area of highest magnetic field density of each magnet is at the same distance from the second pivot axis D2.

More particularly, and as shown in FIGS. 12 to 15, the second magnets are equidistant.

More particularly, the first driving surface 12 comprises at least a first attraction magnet oriented according to the second polarity towards the periphery of the second mobile receiver 2.

More particularly, the first driving surface 12 comprises at least a first ferromagnetic portion in the vicinity of the periphery of the second mobile receiver 2. It may include in particular one or more magnets, and one or more ferromagnetic parts.

More particularly, the first holding surface 11 comprises a plurality of first repulsion magnets oriented in the first polarity towards the periphery of the second mobile receiver 2.

In the variant illustrated in FIGS. 12 and 13, the receiving magnets 21, the magnetized track of first polarity constituting the first holding surface 11, and the second polarity track constituting the first driving surface 12, have a magnetization oriented in the median plane PM.

In the variant illustrated in FIGS. 14 to 16, the receiving magnets 21, the first polarity magnetized track constituting the first holding surface 11, and the second polarity track constituting the first driving surface 12, have a magnetization oriented parallel to the first pivot axis D1.

These particular orientations of magnetization are not limiting. They depend on the space available inside the watch, for optimal positioning of the wheel of passage. If necessary, the magnetization direction may be oblique, in particular according to a conical surface, or the like.

The invention also relates to a timepiece mechanism 500 comprising at least one such sequencer mechanism 100, and comprising first drive means for driving at least a first mobile blocker 1 of a sequencer mechanism 100. And, when the second mobile receiver 2 of a sequencer mechanism 100 is not subjected to a motor torque in accordance with the engine torque of the corresponding first mobile blocker, the sequencer mechanism 100 concerned is made in the mechanical alternative according to the variant of FIGS. . 6 to 10, or is realized in the magnetic alternative.

More particularly, the watch mechanism 500 comprises second driving motor means subjecting a second mobile receiver 2 of a sequencer mechanism 100 to a torque around the second pivot axis D2, in agreement with the engine torque at which is subjected the first mobile blocker 1 corresponding to the same sequencer mechanism 100, so as to provide additional torque to the first mobile blocker 1 during the rotation of the second mobile receiver 2 under the action of a first driving surface 12 of the first mobile blocker 1.

The invention also relates to a timepiece, in particular a watch 1000, comprising at least one such watch mechanism 500, or / and at least one such sequencer mechanism 100.

The figures illustrate non-limiting embodiments.

Figs. 1 to 11 illustrate variants of the mechanical type, with a passage wheel, which is the second mobile receiver 2, which is equipped with rollers. In this case, the contact between the passage wheel and the first blocking mobile 1 is preferably effected through a roller 21 which rolls without sliding on the first holding surface 11, and pivots itself in a pivot of the passage wheel 2. In the holding position in FIG. 3, at least the roller 21A, or the two rollers 21A and 21D bear against the first holding surface 11. At the time of the passage of the discontinuity that constitutes the drive surface 12, as visible in FIG. 4, the roller 21A can penetrate into the notch of the first blocking mobile 1, and the passing wheel 2, under the influence of a torque shown in FIG. 4 by an anti-clockwise arrow, in accordance with the rotation of the first mobile blocker 1, can rotate one step, or a quarter turn in this example where the second mobile receiver 2 carries four rollers 21 equidistant to 90 °. The roller 21B then bears, as well as the roller 21A which served as a pivot, on the first holding surface 11, as visible in FIG. 5, until the arrival of the drive surface 12, which is the same in this particular case of the figures where the notch 12 is unique.

In the case of FIGS. 1 to 5, the shape of the first mobile blocker 1 does not ensure the driving of the passage wheel 2, if it is not subject to a one-way torque. But by modifying the shape of the first mobile blocker 1 in the manner of the Maltese cross, with the help of a protruding finger 15 as explained above, it is possible to guarantee this training even in the absence of torque. or if the torque is not in the desired direction, ie in the opposite direction to the imposed rotation. In the holding position in FIG. 6, two rollers 21A and 21D are resting on the first holding surface 11. At the arrival of the discontinuity 12, as visible in FIG. 7, the roller 21A can be inserted into the first notch 13 of the first blocking mobile 1, and the finger 15 bears on this roller 21A to rotate the passage wheel 2 by a first part of its pitch, and the bring to the position of fig. 8. In fig. 8, the first rotation of the passage wheel 2 has brought another roller 21B to the finger 15, which guides it into the second notch 14, which drives the roller 21B and thus the passage wheel 2 in a complementary rotation such as visible on the figu. 9, thus performing the second part of his step. The roller 21C then bears, as well as the roller 21B which served as a final pivot, on the first holding surface 11, as visible in FIG. 10, until the arrival of the drive surface 12, which is the same in this particular case of the figures where it, composed of two notches 13 and 14 and the finger 15, is unique. Here, the passage wheel 2 has rotated 180 °.

This variant of FIGS. 6 to 10 therefore allows the passage, even if the passage wheel 2 is not subjected to a torque in the direction for its drive.

Figs. 12 to 16 illustrate variants of magnetic type, with a passage wheel, which is the second mobile receiver 2, which is equipped with magnets, and which is non-contact, which is even more favorable than the lightened contact mechanical variants . The figures differentiate the marks 4 and 5 according to the polarities: + or North in 4, - or South in 5.

In this embodiment, the magnets 21 of the passage wheel 2 are in repulsion with the magnets of the first mobile blocker 1. The position of the passage wheel 2 is locked in a stable position, despite the torque that tends to turn it (counter-clockwise in Figures 12 and 13). At the moment of the passage of the magnets of the first mobile blocker 1 whose direction of magnetization is opposite, the magnets 21 of the passage wheel are attracted, and the passage wheel can turn a step, a sixth of a turn in the case illustrated.

The examples of FIGS. 12 and 13 illustrate the case where the magnets have a magnetization oriented in the plane.

In an alternative embodiment, the same principle can be applied for magnets whose magnetization is oriented along the first pivot axis D1, as shown in FIGS. 14 to 16. In this particular case, the passage wheel 2 has two levels of magnets in attraction, at two median planes PM1 and PM2. It is quite possible to have two levels on the first mobile blocker 1 rather than the wheel of passage on the same principle. The solutions proposed above make it possible to let a passing wheel run under torque alternately, and by limiting the consumption when the passing wheel does not rotate (at rest). Many applications are possible with this type of system.

Naturally, it is possible to reverse the magnetic alternative, with a holding position by attraction, and a drive by repulsion, however this solution may include instability, which requires significant torque on the first mobile blocker to compose such instability.

A first application relates to a temporary contribution of torque. Indeed, in many cases, watch movements have complications that generate additional torque consumption, but over a limited period of time. This is particularly the case of simple, annual, perpetual, or other calendar mechanisms, which consume energy during the movement of the date, usually at midnight. This consumption implies a local fall in amplitude and therefore a decrease in the power reserve.

The described system may constitute a contribution of torque during this time interval of overconsumption. If the passage wheel 2 is connected to an auxiliary barrel 3, smaller in size than the main barrel, or even a simple spiral spring or a blade, or any elastic or magnetic return means, and the first blocking mobile 1 is connected directly or indirectly to the work train and dimensioned to achieve a turn in 24 hours (if the over-consumption occurs only once in 24 hours), then the passage wheel 2 can bring a torque to the first mobile blocker 1 during the consumption interval and thus to avoid a fall in amplitude at the passage of midnight and thus to increase the power reserve. This variant is illustrated in FIG. 11.

Another example of application relates to a torque variator. In the case of a system, in particular differential, which allows to change the torque ratio between two mobile, for example barrel / center, in particular to make the torque constant when disarming the barrel, it is necessary to drive in rotation a lever, or a carrier-satellite, so that it adapts the position of the satellite according to the disarming state of the cylinder. This lever is therefore subject to a couple that is necessary to support. The passage wheel 2, driven alternately in rotation by the first blocking mobile 1, which is in this example the barrel drum, can drive this lever which therefore transmits a significant torque. The solution according to the invention makes it possible to maintain the passage wheel 2 fixed, with a limited consumption despite the torque to which it is subjected.

Very many applications are possible, including and not limited to: - watch movements including a consummation consuming torque at regular intervals, for example every 24h; watch movements comprising a torque variator, for example to achieve a constant force; watch movements comprising an alternating drive system, for example cams leap years in a perpetual calendar, to reduce the torque consumption; chronographs comprising a minute counter or hour counter, with alternating drive, to reduce the torque consumption.
