Definitions

  • the present invention also relates to a watch movement comprising a watch mechanism associated with such a control device, in particular a chronograph mechanism, as well as a timepiece comprising such a watch movement.
  • Control devices of this type are already known in the prior art, in particular in relation to chronograph mechanisms.
  • the device comprises a reset trigger lever comprising a nozzle arranged to pivot a stepped mobile.
  • the trigger lever comprises a nozzle arranged to cooperate with a stop provided on a first board of the stepped mobile defining a first stage of the latter.
  • the stepped mobile comprises a second board defining a second floor, this having a general shape of a heart-shaped cam arranged to cooperate with a control lever making it possible to define the angular orientation of the stepped mobile.
  • the control lever undergoes the action of a spring making it possible to maintain a roller which it carries at one of its ends in permanent support against the periphery of the second board.
  • the latter includes a recess making it possible to define an angular orientation of rest of the stepped mobile when the roller is housed there, in the absence of an action by a user.
  • the movement of the latter causes a rotation of the stepped mobile, the roller then emerging from the recess and rolling along the periphery of the second board.
  • the latter then presents an increasing radius until it reaches the tip of the heart cam.
  • the spring tenses, storing mechanical energy.
  • the roller crosses the tip of the heart cam, and the spring can release the mechanical energy previously stored, by becoming a motor, to further rotate the stepped mobile and carry out the reset. zero of the chronograph mechanism.
  • the stepped mobile comprises a third board, defining a third floor, on which a zeroing surface is provided, this being intended to cooperate with a zeroing cam of the chronograph mechanism, in a conventional manner .
  • the stepped mobile continues its rotation under the impulse of the spring until the roller returns to position itself in the recess of the second board.
  • One aim of this device is in particular to ensure that the reset cam is released immediately after being returned to its zero position, to achieve a return in flight, even if the user maintains action on the trigger lever.
  • this complex construction provides that the spring is loaded by moving the trigger lever but can be unloaded by rotating the third board, defining an actuating member of the chronograph mechanism, independently of the position of the trigger lever. If the user does not actuate the trigger lever until it reaches its trigger position, the stepped mobile moves backwards under the effect of the action of the spring, until the roller stops. reposition in the recess of the second board.
  • this construction makes it possible to guarantee that the resetting of the chronograph mechanism is complete when the travel of the trigger lever is complete, which makes the corresponding control device an "all or nothing" type device.
  • control device having an "all or nothing" type of operation of simplified construction with reference to existing devices.
  • a main aim of the present invention is to propose an alternative construction control device to the constructions known from the prior art, presenting in particular greater simplicity both in terms of number of components and assembly.
  • the locking member is arranged to perform back-and-forth movements during configuration changes, thus further limiting the bulk of the control device according to the invention.
  • the lever is also arranged to act on the actuating member and move it towards its neutral position when it itself moves towards its rest position.
  • the energy storage member can be made in one piece with the actuating member and has a portion arranged indirectly or directly in support against the lever.
  • the lever includes a stop arranged to act on the locking member and move it from its locking configuration to its neutralized configuration in response to the user's action on the control member. external.
  • the additional elastic return member is intended to be integral with a frame element of the watch movement by being arranged to exert a return force on the board and tend to bring back the locking member from its neutralized configuration to its locking configuration.
  • the present invention also relates to a watch movement comprising a watch mechanism associated with a control device according to the above characteristics, more preferably when the watch mechanism is a chronograph mechanism, as well as a timepiece comprising such a watch movement .
  • THE figures 1 to 4 represent simplified front views of a control device 1 according to a preferred embodiment of the present invention, in four configurations which it successively occupies when activated by a user.
  • the control device 1 comprises a lever 2 intended to be mounted on a frame element (not shown) of the corresponding watch movement, so as to be able to pivot along an axis of rotation defined by its mounting screw 4 on the frame element .
  • the lever 2 has a first arm 6 extending from its axis of rotation and intended to receive a force exerted by a user, transmitted to the first arm 6 via an external control member (not visible) of the part corresponding timepiece, preferably a conventional pusher.
  • an external control member not visible
  • the lever 2 pivots clockwise on the view of the figures 1 to 4 .
  • the lever 2 comprises a second arm 8 intended to cooperate with an actuating member 10 of a watch mechanism of the corresponding watch movement. More precisely, the second arm 8 of the lever 2 carries a stop member, here a screw 12, arranged projecting on the second arm 8 so as to be able to cooperate with the actuating member 10 when the lever 2 pivots.
  • a stop member here a screw 12
  • the screw 12 can be replaced by a simple pin, but the use of an eccentric screw, as is the case here, advantageously makes it possible to offer a possibility of adjusting the relative orientation between the second arm 8 and the actuating member 10.
  • the lever 2 is advantageously associated with an elastic return member, here a straight spring 14 made in one piece with the first arm 6 and the free end of which is intended to rest on a pin 16, integral with the movement frame watchmaker, to tend to rotate lever 2 in the direction of anti-clockwise rotation as shown in the figures.
  • an elastic return member here a straight spring 14 made in one piece with the first arm 6 and the free end of which is intended to rest on a pin 16, integral with the movement frame watchmaker, to tend to rotate lever 2 in the direction of anti-clockwise rotation as shown in the figures.
  • the lever 2 occupies a rest position by default, which may in particular be defined by a stop not shown (for example provided on the plate or the caging circle, or even on the box of the corresponding timepiece, or even directly ensured by the external control unit).
  • the actuating member 10 comprises two contact surfaces arranged on either side of the eccentric screw 12, in such a way that the lever 2 can act on the actuating member 10 to make it pivot. in one direction of rotation or the other.
  • the actuating member 10 has a base 18 provided with a central opening 20 intended to allow the assembly of the actuating member 10 on the frame of the corresponding watch movement, while defining the axis of rotation.
  • a first arm 22 extends from the base 18, in a generally radial direction, and has a central portion 24 capable of cooperating with the eccentric screw 12 of the lever 2 to define one of the contact surfaces mentioned above.
  • the actuating member 10 also comprises a spring 26, extending here from the first arm 22 by way of non-limiting example, and whose free end 28 defines the second contact surface cooperating with the screw 12 of lever 2.
  • the first arm 22 presents, after its central portion 24 and moving away from the base 18, a curved terminal portion 30 whose free end defines a nose 32 of substantially tangential orientation (with reference to the axis of rotation of the actuating member 10).
  • the actuating member 10 also comprises a second arm 34 intended to actuate the associated watch mechanism (not shown) when the actuating member 10 pivots, here in the direction of anti-clockwise rotation in the view of the figures 1 to 4 .
  • the second arm 34 is mentioned here by way of non-limiting illustrative example, and those skilled in the art will not encounter any particular difficulty in adapting the actuating member according to their own needs without departing from the framework of the invention.
  • the actuating member comprises a plurality of arms intended to cooperate with one or different mechanisms and/or that the actuating member carries stops, possibly of different types, intended to cooperate with one or different mechanisms (we have illustrated here by way of example five pins 35, including one at the end of the second arm 34, and an eccentric 37, which can actuate the same mechanism in different ways and/or at different times, or which can activate different mechanisms).
  • the control device 1 also comprises a locking member 36 intended to be mounted on the frame of the watch movement so as to be able to pivot along an axis of rotation defined by its mounting screw 38 on the frame.
  • the locking member 36 has the shape of a board located opposite the nose 32 of the actuating member 10 and provided with a slot 40 into which the nose 32 is capable of penetrating as will emerge from the rest of this description.
  • the board of the locking member 36 carries a pin 42 defining a stop for an additional elastic return member 44, the latter being arranged to maintain the locking member 36 in a locking configuration ( figures 1 and 2 ), that is to say a configuration in which the slot 40 is not located opposite the nozzle 32 of the actuating member 10.
  • the board has an extension 46 arranged to cooperate with a pin 48 secured to lever 2, in such a way that rotation of lever 2 in the direction of clockwise rotation, in the view of the figures 1 to 4 , can cause a rotation of the locking member 36 in the direction of anti-clockwise rotation, to possibly cause it to pass into a neutralized configuration, that is to say a configuration in which the slot 40 is located opposite the spout 32, thus allowing the actuating member 10 to pivot.
  • the elastic return member of the locking member can be made in one piece with the board of the latter and cooperates with a pin secured to the frame of the watch movement, without however leaving the frame. of the invention.
  • the additional elastic return member 44 here comprises a base 50 intended to allow its attachment to the frame of the corresponding watch movement, for purposes of illustration.
  • control device 1 The mode of operation of the control device 1 will now be described in relation to its four successive configurations illustrated on the figures 1 to 4 , corresponding to four successive moments during activation by a user, by an adapted action on the external control member of the corresponding timepiece.
  • FIG. 1 illustrates the configuration of the control device 1 in its initial state, at rest, before the user's action has an impact on it.
  • Lever 2 is held in its rest position due to the action of spring 14 which tends to make it pivot in the direction of anti-clockwise rotation in the view of the figure 1 .
  • the pin 48 of the lever 2 defines a stop for the locking member 36, in combination with the action of the additional elastic return member 44, to hold the locking member 36 in its locking configuration, that is to say a configuration in which its slot 40 is not located opposite the nozzle 32 of the actuating member 10.
  • the eccentric screw 12 of the lever 2 is positioned in support against the central portion 24 of the first arm 22 of the actuating member 10, the lever 2 thus ensuring that the actuating member 10 is maintained in a neutral or rest position.
  • the free end 28 of the spring 26 is preferably positioned against the eccentric screw 12 in this configuration, the spring 26 being slightly preloaded for this purpose.
  • FIG. 2 illustrates the configuration of the control device 1 once the lever 2 begins to rotate, in the direction of clockwise rotation, in reaction to the user's action on the external control member.
  • the actuating member 10 undergoes a stress in the direction of anti-clockwise rotation on the view of the figure 2 , by action of the eccentric screw 12 on the free end 28 of the spring 26, causing its nose 32 to be maintained against the board of the locking member 36 (or its support if play was provided at rest). Even if the locking member 36 has also started to rotate, in the direction of anti-clockwise rotation, the angle traveled is not sufficient to position the slot 40 facing the nozzle 32 of the actuating member 10 Also, the nozzle 32 remains firmly supported on the periphery of the board of the locking member 36, the latter therefore always being in the locking configuration in which it ensures the locking of the actuating member 10.
  • spring 14 of lever 2 gradually tightens.
  • spring 26 is deformed under the effect of the action of the eccentric screw 12 of the lever 2.
  • the spring 26 then fulfills the role of a mechanical energy storage, interposed between the lever 2 and the actuating member 10, so as to be able to charge when the lever 2 moves from its rest position to a final triggering position.
  • the control device 1 would return directly to its state initial, as shown on the figure 1 .
  • the lever 2 would be returned to its rest position due to the combined action of the springs 14 and 26, the eccentric screw 12 then repositioning itself in support against the central portion 24 of the first arm 22 of the member d actuation 10.
  • the locking member 36 can pivot in the direction of clockwise rotation until it resumes its initial angular orientation, under the effect of the action of its additional elastic return member 44.
  • control device 1 switches to the configuration illustrated on the Figure 3 , in which its lever 2 has reached its trigger position.
  • the locking member 36 continued its rotation in the direction of counter-clockwise rotation in the view of the figures 2 And 3 , until positioning the slot 40 opposite the nozzle 32 of the actuating member 10. At this instant, the latter suddenly becomes free to pivot in the direction of anti-clockwise rotation, which the mechanical energy stored up to here in the spring 26 encourages it to do quickly, as appears from the configuration illustrated on the Figure 3 .
  • the travel traveled by the eccentric screw 12 when the lever 2 passes from its rest position to its triggering position, corresponds at least to the travel traveled by the nozzle 32 to reach the screw 38 of the locking member 36 , when the actuating member 10 passes from its locked position illustrated on the figure 2 to its actuation position illustrated on the Figure 3 .
  • the central portion 24 of its first arm 22 approaches the eccentric screw 12, without necessarily being in contact with it.
  • the second arm 34 (and any other possible stop, as mentioned above) of the actuating member 10 also moves in the counterclockwise direction, in the views of the figure 2 And 3 , to operate the watch mechanism(s) with which the control device 1 is associated, for example a member for resetting one or more chronograph counters.
  • the amplitude of the movement of the actuating member 10, and therefore of its second arm 34 does not depend directly on that of the lever 2.
  • the triggering of the actuation of the associated watch mechanism is conditioned by the amplitude of movement of the lever 2, which must move until it reaches its position of triggering.
  • the lever 2 pivots in the counterclockwise direction on the view of the figure 4 , under the effect of the action of its spring 14.
  • the lever 2 acts on the actuating member 10 by applying pressure by the eccentric screw 12 on the central portion 24 of the first arm 22, thus pivoting the actuating member 10 in the direction of clockwise rotation to bring it back to its neutral position.
  • the lever 2 releases the locking member 36, its pin 48 moving away from the extension 46.
  • the locking member 36 remains blocked in its neutralized configuration as long as the nose 32 is engaged in its slot 40 and therefore prevents its board from rotating.
  • the elastic return member 44 of the locking member 46 thus remains taut as long as the nozzle 32 has not emerged from the slot 40.
  • the additional elastic return 44 rotates the locking member 36 in the direction of clockwise rotation on the view of the figure 4 to return it to its locking configuration, the entire control device 1 thus resuming its initial configuration as illustrated on the figure 1 .
  • the locking member 36 makes a back and forth movement each time the control device 1 is activated by the user, which makes it possible to further limit the bulk of the device according to the present invention.
  • control device is perfectly suitable for implementation with operating parameters adapted to a conventional chronograph mechanism, in particular a stroke of the corresponding pusher of the order of 0.8 to 1 mm and a force actuation of the order of 8 to 12 N, it can also be implemented with particular mechanisms having reduced operating values, for example a pusher stroke of the order of 0.3 mm and a force of the order of 1.5 to 2.5 N.
