    Description: BACKGROUND OF THE INVENTION The invention relates to a device for restoring, in a predetermined position, an indicator member of a magnitude related to the time or temporal magnitude, in particular a "Flyback" or flight return device. The invention also relates to a watch movement or a timepiece equipped with such a device.
    There are on the market a number of wristwatches whose second second hand can be reset and then start immediately. This function is commonly called "flyback" or "return flight", and must be distinguished from the mechanisms of catch-up, which are sometimes also referred to by the term "flyback".
    Such a function is commonly performed by a synchronous reset device and controlled by a control member whose actuation induces the resetting of the second hand, and whose release causes its restart. This must be distinguished from a non-synchronous reset device whose action of a control member induces, on the one hand, the reset of the second hand, and secondly , its restart. As shown in FIG. 1, the operation of the synchronous mechanism is synchronized with the handling of the wearer of the wristwatch, the pressing of a pushbutton causes the reset and release causes the restart of the second hand. As a result, the speed of execution of the timing is dependent on the dexterity of the user. The functionality of such a device is therefore limited compared to that of a non-synchronous reset device. In addition, this synchronous device is generally reported on chronograph mechanisms. In this case, the flyback mechanism is dependent on the chronograph clutch system and the large number of components required to operate it. Another solution is to ride the second second hand within the basic movement. This construction has the advantage of implementing few parts and does not require clutch. However, the friction is subject to wear and prolonged actuation of the control member may disrupt the chronometry of movement, or even cause a stop of the watch. Indeed, the friction induces a consumption of energy which is punctured on the energy necessary for the good chronometric operation of the movement.
    CH 183 262 describes a modification of a chronograph mechanism with horizontal clutch. Hammers are adapted to allow disengagement of the counting chain during an untimely reset without stopping the chronograph. Releasing a pushbutton disconnects the failures of a reset core hammer and causes the counting chain clutch to re-engage. This mechanism is dependent on the completeness of the basic chronograph mechanism. In addition, the proper functioning of such a system requires a large number of adjustments, and does not allow the implementation of a non-synchronous reset device.
    The document CH 214 664 relates to a horizontal clutch device devoid of triggering system (flip-flops and trip levers and column wheel). A control member is in direct contact with a flyback mechanism. Pressing a push button induces the movement of a hammer which, in one operation, acts on a resetting heart and disengages the counting chain which is arranged on a rocker of the kinematic chain of the movement. The release of the push button allows the restart of the second hand second. Despite a reduced number of components compared to the usual chronograph mechanism, the synchronization of the zeroing and the clutch control is particularly difficult to develop. Moreover, such a system does not allow the implementation of a non-synchronous reset device.
    EP 1 136 894 A1 discloses a vertical clutch chronograph mechanism which comprises a hammer designed to actuate additional clutch means in case of reset in flight. The mechanism is disengaged, and the second hand is reset until the user presses a push button. The proper functioning of this mechanism is dependent on the development of the vertical clutch, and furthermore requires an additional command to operate it. Moreover, such a system does not allow the implementation of a non-synchronous reset device.
    The document FR 1 104 103 describes a device without clutch. A second second hand is frictionally mounted on a second gear. Pushing a push button induces the action of a hammer that acts on a reset heart of the second hand. The friction generated between the second gear and the second hand continues until the user has released the push button. This synchronous device thus has the risk of disrupting the chronometry of the movement, or even causing a stop of the watch. The hammer is brought back into position by a wire spring when releasing the push button. The second hand is then rotated again. In fact, this system does not allow the implementation of a non-synchronous reset device.
    [0008] Document CH 698 827 describes a synchronous reset device. This implements a control member which is provided to cooperate with a return spring so as to allow the return to the rest position of the hammers once the control member is no longer actuated. Such a system therefore does not allow the implementation of a non-synchronous reset device.
    [0009] Document CH 702 157 describes a simplified chronograph device whose actuation of the single control member induces zeroing of the second and minute hands, and whose release causes them to restart. The system is reduced to the horizontal clutch mechanism of the chronograph and to the zeroing device which are adapted to allow the disengagement of the counting chain when actuating the hammers on the cores. Such a system allows the implementation of a synchronous reset device by a suitable reset device, but does not allow to adapt the control member, the horizontal clutch, and the hammers so as to define a non-synchronous reset device.
    The document CH 678 910 describes an adaptation of at least two hammers so as to allow the adjustment of their positioning vis-à-vis their respective heart. This document does not disclose elements for conforming these hammers so as to possibly incorporate them into a system intended to equip a non-synchronous reset device.
    EP 1 936 448 discloses a display device at the request of a time indication controlled by a pusher. The system includes a cam, a cam follower integral with a rake, and a pinion which is engaged with the rake. The latter is recalled by a return spring when the push button is no longer actuated. It is thus a device whose control member is perfectly synchronized with the display device.
    In view of these documents, these solutions lead to the implementation of synchronous reset devices whose return elements, namely hammers or rakes, are actuated directly by a control member, possibly by a control device combined with a return spring, independently of any third-party device. In fact, these solutions do not allow the implementation of a non-synchronous reset device whose action of a control member induces, on the one hand, the return to predetermined position of an indicator organ. of a magnitude related to time, and secondly, its restart.
    The document CH 192 624 describes an embodiment of a flight return device which has the specificity of being non-synchronous: it is the pushing action of a push button that allows the reset of the second hand, then its restart. The action of the pushbutton is transmitted to a reset hammer via a cam and a control lever. The cam is rotatable and cooperates with a return spring. The latter has an inclined surface provided to cooperate with the control lever during the reset. The action of the hammer on the heart is interrupted once the control lever has reached the end of the inclined plane. The spring that cooperates with the cam allows it to retract so as to interrupt the action of the control lever on the hammer which returns to its initial position under the action of a second return spring, that the push button is still in a hurry or not. This mechanism does not, however, cancel out the risk of trailing zero of the second hand, and also does not eliminate the risk of stopping the second for a long time, and thus to disrupt the movement. In addition, no device is provided to generate a frank sensation that can be felt by the user from the beginning of the activation of the push button. Finally, a partial depression of the push button may cause a partial return of the second hand to its zero position, by the action not complete hammer on the heart. Such a possibility is not desirable.
    In view of these documents, and more particularly in view of the last document above, none of the solutions can lead to the implementation of a reliable non-synchronous reset device that allows a single and even an instantaneous reset and instant restart of an indication related to time, for example the second, and this independently of the manipulations of the user.
    The object of the invention is to provide a device for returning to a predetermined position of an indicator member, preferably non-synchronous, overcoming the disadvantages mentioned above and improving the predetermined position reset devices known from the prior art. . In particular, the invention proposes a predetermined relocation device, reliable and allowing in one and the same operation of the user, for example a support on a push button, a return to a predetermined position of an indicator member d a quantity related to time, for example a second hand.

    A first embodiment of a delivery device 100 in a predetermined position of an indicator member 13 of a magnitude related to time is described below with reference to FIGS. 2 to 9. This device is intended to equip a watch movement, including a movement of a wristwatch. For example, this device is a "flyback" device or return in flight to return to a predetermined position a second indication needle or any other size of time. In particular, the predetermined position may be an initial position or a position indicating zero or any other origin. Preferably, the action of the device is controlled by a single action of a user, in particular a support action of the user on a push button. This action of support of the user on the push button allows, as shown in FIG. 2, to cause the return of the indicator member to the predetermined position, then resume the drive of the indicator member in a period of the order of one-tenth of a second. This resumption of training is therefore considered instantaneous, and does not depend on the release of the push button by the user, but only the time required for the device to complete the function initiated by the action of the user. Holding the pushbutton in the down position then has no effect on the operation of the indicator member. In the same way, the release of the push button has no effect on the march of the indicator organ. The resumption of the drive is therefore independent of the position of the control member.
    The indicator member 13 is kinematically linked by friction to a driving wheel 15. This drive wheel is itself driven by a motion transmission chain, comprising a wheel 19 in known manner, from a drive member such as a barrel. Thus, in the absence of actuation of the reset device in a predetermined position, the indicator member of a quantity related to time is permanently driven in motion because it is kinematically linked by friction to the drive member.
    The predetermined position reset device mainly comprises an energy accumulator 9 and a return element 1 of the indicator member of the magnitude related to the time in the predetermined position. The return element is actuated or activated by energy from the accumulator. The repositioning device further comprises a movement transmitting element of the energy accumulator to the biasing element and a power transmitting element to the energy accumulator and triggering the actuation or the activation of the return element. The transmission of energy to the accumulator can be carried out from a pusher 4. The triggering of the actuation or the activation of the return element can be controlled by an action on the pusher. This pusher is manipulable by a user and able to act on the energy transmission element to the energy accumulator and triggering the actuation or activation of the return element.
    The return element comprises a hammer 92 adapted to act on a cam 2, in particular a heart cam or a heart, kinematically connected in rotation to the indicator member 13 and rotatably mounted about an axis 1 '. The core 2 is preferably fixed to the indicator member 13. When the return member is actuated or put into operation, the hammer performs, as described below, a rotational movement about the axis 1 ', in particular a rotational movement of a lathe or a rotational movement of a half-turn. The hammer includes a fault 92a for cooperating with the heart and acting on a portion of the profile thereof to cause its rotation until the indicator member reaches the predetermined position. Furthermore, the hammer comprises a securing element 92b intended to cooperate with a portion of the profile of the heart to immobilize it and thus to immobilize the indicator member in the predetermined position. The hammer generally has the shape of a disk having a notch forming the fault 92a and a clearance 92c allowing the free rotation of the heart about the axis 2 'when the hammer is in a rest position. Unlike hammers mounted pivoting about axes known from the prior art, the hammer moves in a single direction of rotation. It performs, for example, a turn on itself or a fraction of a turn. It does not return to its original position by reversing the direction of its displacement or rotation. The hammer moves unidirectionally during its actuation, that is to say from its rest position to its rest position via a contact position with the heart with which it cooperates.
    The motion transmission element of the energy accumulator 9 to the biasing element 1 comprises a first cam 7 kinematically connected to the biasing element, in particular cinematically connected to the hammer. In particular, the first cam 7 can be fixed to the hammer. The first cam 7 is rotatable about the axis 1 '. The motion transmission element also comprises a roller 8a biased in contact against the first cam 7 by the energy accumulator, in particular by an elastic element, such as a leaf spring 91 of the energy accumulator. This roller is free to rotate and is intended to roll on the profile of the first cam 7. For example, the roller 8a is rotatably mounted on a lever 8 pivotally mounted about an axis 8 '. In this case, the spring 91 acts on the lever to return the roller 8a against the first cam 7. Alternatively, the lever 8 and the spring 91 can be merged into a single piece, and the end of the lever 8 can cooperate with the profile of the cam 7, independently of the roller 8a.
    The element for transmitting energy and triggering the activation of the return element comprises a rocker 3 and a second cam 6. The second cam 6 is kinematically connected in rotation to the return element 1 For example, the second cam 6 is fixed to the first cam 7. This attachment can be made, as shown, by a notch on the second cam cooperating with a pin on the first cam 7. The rocker 3 is able to act on the second cam 6 to cause its rotation. To do this, the second cam 6 comprises a notch 6a intended to cooperate with the rocker 3 and more exactly, with a finger 5 pivotally mounted about an axis 5 'and returned to a rest position, against a stop 12, by an elastic element 11. The finger 5 is retractable. Thus, the rocker 3 acts on the second cam 6 via the finger 5. The rocker is pivotally mounted about an axis 3. The pivoting of the rocker is caused by the translation of the pusher 4 when it is actuated by the This actuation of the rocker is made against the action of a return spring 10. This spring makes it possible to return the rocker to a rest position when there is no longer any action on the pusher. , its functionality is equivalent to that of the springs which are provided to cooperate with the return elements and / or the control members of the reset devices known from the state of the art.
    The pusher can of course be replaced by any type of control member.
    The indicator member 13 and the core 2 can be driven on an axis 14 as shown in FIG. 9. The wheel 15 of the indicator member 13 is frictionally mounted on this assembly by means of a spring 16 to allow the clutch of the indicator member vis-à-vis the transmission chain during a returning to the predetermined position of the indicator member. The friction spring 16 is dimensioned so as to keep the indicator member 13 and the wheel of this indicator member 15 integral in the event of an accidental shock, but it is also intended to allow, in all cases, the return to a predetermined position. the indicator member with the energy accumulated by the spring 91. Optionally, a flyweight 17, integral with the axis 14, advantageously counterbalance the unbalance due to the indicator member and thus minimize its impact sensitivity.
    As shown in FIG. 2, a device for returning to a predetermined position of an indicator member as described above can equip a watch movement or a timepiece.
    The operation of the predetermined position reset device is described below with reference to FIGS. 4A to 8 (which detail the operation of the energy transmission element to the energy accumulator and the activation of the actuation of the return element) and 11 to 18 (which detail the operation of the element of recall and its interaction with the indicator organ).
    FIG. 4A illustrates the energy transmission element at rest, when the user does not act on the pusher 4. The actuation of this pusher causes, as shown in FIGS. 4B, 5, and 7A, the pivoting of the rocker 3 about the axis 3 'against the action of the spring 10. This pivoting causes an action of the fingers on the second cam 6 at the notch 6a. This action causes the rotation of the second cam 6 about the axis 1 '. The rotation of the second cam 6 about the axis 1 'causes that of the first cam 7 about the same axis. It follows as shown in figs. 5 and 7A that the roller 8a leaves its rest position defined by a first portion 7a of the first cam and reaches a second portion 7b of the second cam. The rest position defined by the first portion 7a allows, by the action of the spring 91, to immobilize the first cam 7 in rotation, and thus to immobilize the hammer in rotation when the control member 4 is not operated. While traveling on the second portion 7b, the roller 8a moves away from the axis 1 'of rotation of the first cam. It follows a pivoting of the lever 8 and therefore a deformation of the spring 91 which stores energy supplied by the user during the manipulation of the control member 4. This energy is accumulated via the second profile 7b the first cam 7 which rotates over an angular range Φ of the rest position illustrated in FIG. 11 to a position shown in FIG. 12 where the roller 8a reaches a junction 7d between the second profile 7b and a third profile 7c. Until this position, the second cam 6 is always rotated by the action of the rocker 3 by means of the finger 5. This third profile 7c is of the spiral or spiral type. Thus, as soon as the roller 8a arrives on this profile, as shown in FIGS. 7B, 13, 14, 15, 16, 17 and 18, the action of return against the first cam 7 causes a mechanical action of the roller 8a on the first cam 7 by creating a mechanical torque around the axis of rotation 1 ' of the first cam 7. It follows that the first cam 7 is then rotated by the energy of the spring 91. No more action is required on the control member 4 and on the lever 3. In particular, the control member 4 can be released. The rotation of the hammer 92 takes place in a time of the order of a tenth of a second when the spring 91 restores the accumulated energy by communicating a rotational movement to the first cam 7 via the lever 8 and its roller 8a which cooperates with the third profile 7c. In the case where the control member is not released, the rotation of the hammer 92 does not interfere with the rocker because, as shown in FIG. 8, the rotation of the second cam 6 is provided to unclip the finger 5. To do this, the finger 5, pivoted 5 'on the rocker 3, cooperates with the spring 11 and a stop 12, mounted on the frame, which hold it in position when the control member is not actuated.
    In other words, as the hammer 92 does not interfere with the core 2, the indicator member 13 is rotated by the transmission chain via the friction link, as shown in FIGS. 3, 4A and 11 for example. When the user actuates the control member 4 and triggers the energy transmission element formed by the rocker 3 and the finger 5 (FIG 4B), a rotation of the cam 6, and therefore of the hammer 92, is initiated. The roller 8a travels along the second profile 7b of the cam 7 and arrives at the junction 7d of the second and third profiles of the cam 7 as illustrated in FIGS. 5 and 12. This cam then traveled an angle Φ from its initial position which is shown in FIG. 11. Once this phase of accumulation of energy is completed, the roller moves along the third profile 7c of the cam 7 to the first contact between the surfaces 92a of the hammer 92 and 2a of the core 2. This displacement corresponds to a rotation of an angle of the first cam 7 as shown in FIG. 13. The fault 92a of the hammer 92 then acts on a surface 2a of the core 2 to return the indicator member 13 to a predetermined position as shown in FIG. 14. There is then sliding at the friction connection, the drive wheel 15 is still driven. After a rotation of an angle β, a hammer securing profile 92b comes into contact with a core profile 2c as shown in FIGS. 15 and 16. The indicator member has been returned to a predetermined position and is immobilized in this position while the hammer is traveling through an angular arc δ as shown in FIG. 17. Once this angular path has been achieved, the hammer no longer interferes with the core, and the indicator member is rotated again via the friction link from the predetermined position as shown in FIG. 18. The hammer and the first and second cams then continue their rotation on an angular arc γ until the roller 8a returns to the first profile 7a of the first cam as shown in FIG. 19.
    The amplitudes of the angular ranges are of course a function of the relative position of the core 2 vis-à-vis the hammer 92.
    The device for restoring predetermined position of the indicator member is designed to overcome the dynamic effects generated by the energy return of the spring 91. To do this, the kinematics and the geometry of the hammer 92 are studied to, firstly perform the setting in position, and, secondly, lock the angular position of the heart 2 after positioning.
    The cooperation between the hammer 92 and the core 2 can be likened to a Maltese cross system during the security phase. In particular, the profiles 92b and 2c may be complementary and formed at least partially of an arc of a circle of radius of curvature comparable or identical.
    With the device according to this embodiment of the invention, an energy accumulator is the interface between the control member and the return element in the predetermined position. An energy produced by the actuation of the control member is transmitted to the energy accumulator and then restored, in particular in a fraction of a second, to the return element in the predetermined position. In other words, the return element is actuated by energy from an accumulator, the energy being previously supplied to the energy accumulator by the control member. In this way, the user can not in any case act directly on the return element in the predetermined position. Such a design thus makes it possible to make the flight return function more reliable, and to avoid any chronometric deterioration due to the friction clutch mechanism.
    When the return element acts on the indicator member of the size related to time, the energy of this action is integrally from the accumulator. This energy has been previously stored in the accumulator by an action of the user, in particular an action of the user on the accumulator via the control member.
    The energy accumulator is a perfectly controlled system. It is therefore easy to design and implement.
    The energy accumulated by the device is that provided by the user. The pusher sensation is therefore frank, and it is dependent on the energy accumulator. A timepiece equipped with such a predetermined position reset device therefore does not require additional mechanism provided to create a force of opposition to the push, as is the case on chronographs known to the state of the art.
    The energy that is transmitted to the hammer allows it to overcome, over all tolerance ranges, the friction torque generated by the friction link which must be sized to keep the indicator member and the wheel of this mobile solidarity. in case of accidental shock.
    The kinematics of the hammer is particularly simple. The triggering of the function causes the hammer to pivot 360 ° (Φ + α + β + δ + γ = 360 °), always in the same and unique direction of rotation. The number of parts needed to drive the hammer is reduced to the essentials.
    The kinematics and the geometry of the hammer are studied to, firstly perform the reset to predetermined position, and, secondly, lock the angular position of the indicator member once its predetermined position found. This device allows to remove cheaply dynamic effects due to the sudden return of energy, and without additional brake mechanism.
    The user has no grip on the rotation of the hammer. The risks of trailing reset and partial reset are therefore canceled.
    The hammer actuates the heart in a fraction of a second, or instantaneously. There is therefore no risk of degrading the chronometric performance due to a prolonged friction torque.
