Definitions

  • the invention relates to a watch movement comprising at least a first and a second function implementing the display of at least first and second information, including tachometric information.
  • a watch movement comprising a mechanism associated with one of the first and second functions, and a selection member movable between the first and second positions, respectively associated with the first and second functions and corresponding to the first set and second respective kinematic links, between the work train and the display mobile, giving rise to opposite directions of rotation and / or different speeds of rotation of the display mobile.
  • the first and second functions are chronograph and countdown functions, the display mobile being intended to ensure the displacements of the display member in a first direction during the activation of the chronograph function and in a second direction when activating the count-down function.
  • the watch movement described above has several disadvantages. It should be mentioned first of all that the countdown timer requires a prior adjustment of the value to be counted down, a value which the movement takes into account in order to determine the function to be activated, which implies a complication in use. It will also be mentioned that such a mechanism has a relatively large number of pieces which involves a relatively complex and difficult mechanism to implement.
  • the invention particularly aims to overcome the various disadvantages of these known techniques.
  • an object of the invention is to provide a tachometer and / or a chronograph to obtain a more accurate reading of the average speed depending on the situation encountered, such as a regatta or a car race.
  • the invention also aims, at least in a particular embodiment, to provide a device that is simple to implement and inexpensive.
  • the object of the present invention by its different functional and structural aspects described above, makes it possible to obtain an organ of relatively compact selection while being relatively simple to implement.
  • the invention also relates to a timepiece equipped with a movement according to the invention.
  • the watch movement 1 is arranged to allow the display of the hour and the minute by means of an hour wheel, a minute wheel, and a second wheel, in a conventional manner.
  • the movement 1 comprises at least one chronograph and countdown mechanism, each mechanism being selectable through the same selection member.
  • the chronograph driving wheel 2 and the mobile chronograph 3 have been represented in the figures in order to better visualize the different kinematic links of the functions.
  • the figure 1b illustrates an exploded view in perspective of a part of a watch movement 1 equipped with a selection member further comprising an actuator 10, one end of which comprises an actuating finger 101 for selecting a function.
  • the other end 100 of the actuator 10 may for example cooperate with a push button actuated by the user.
  • the actuator 10 is slidably mounted on a frame member of the movement to allow the finger 101 to move in a direction longitudinal, and is configured to cooperate with elastic return means, not shown in the figures, so as to maintain it in the rest position.
  • the actuating finger 101 is provided to cooperate with a cam 20 pivotally mounted on a frame member of the watch movement 1 between at least two positions, by an axis of rotation located in the center of the cam 20, one of the positions being associated with the chronograph function and the other with the countdown function.
  • the cam 20 comprises at least a first shuttle, called lower shuttle 21, a second shuttle, called upper shuttle 22, and a ratchet 23, arranged around the same pivot axis.
  • the lower 21 and upper 22 shuttles respectively have a spout 210 and a spout 220 at each of their ends, the spouts being arranged symmetrically with respect to the center of rotation of the cam 20.
  • the selection member also comprises a flip-flop, said first flip-flop 30.
  • the first flip-flop 30 is constituted by a lower plate 31 and an upper plate 32 between which are arranged a first wheel formed by a first axis 33 receiving a gear wheel 330 and a pinion 331 and a second wheel formed by a second pin 34 receiving toothed wheel 340, an upper pinion 341 and a lower pinion 342.
  • the upper plate 32 and the lower plate 31 are assembled together to form the first flip-flop 30, upper plate 32 having an upper pivot 320 configured to be housed in the orifice of a bridge not shown in the figures and the lower plate 31 having an orifice 311 configured to receive a pivot of another bridge.
  • the upper pivot 320 and the orifice 311 are aligned on the same axis so as to form the axis of rotation of the first latch 30.
  • the first wheel and the second wheel are configured to cooperate with the chronograph driving wheel 2 when the selection member is moved between the first and second positions corresponding to the first and second kinematic links.
  • the wheel 330 of the second wheel is engaged with the driving wheel 2 and is kinematically connected to the chronograph mobile 3 through the pinion 331 which engrains an intermediate wheel 430 engraining itself the wheel 340 of the second gear in connection with the lower gear 342 which drives the chronograph mobile 3.
  • the first wheel and / or the second wheel can be gear reducers and / or inverters depending on the functions that it is desired to implement within the watch.
  • These functions can be, for example, a chronograph function, a countdown function, or a chronograph function with a lower speed.
  • the lower plate 31 of the first rocker 30 has an engagement surface configured to cooperate with the cam 20. More specifically, the nozzles 210 of the lower shuttle 21 are configured to cooperate with the engagement sector 310 of the lower plate 31 to move in rotation the first latch 30.
  • the carrier presses a push button, not shown in the figures, in connection with the actuator 10 so that that the actuating finger 101 rotates the ratchet 23, and the lower shuttle 21 which then bears against the engagement sector 310.
  • This has the effect of pivoting the first latch 30, to disengage the upper gear 341 of the chronograph driving wheel 2 and simultaneously engage the wheel 330 with the chronograph driving wheel 2.
  • a spring blade 11 is provided to hold the ratchet 23 and to advance it stepwise when it is actuated in rotation by the actuator 10.
  • the selection member comprises a second spring blade 12 configured to define a default position of the first latch 30, exerting on it a force to place it in the position associated with the first function, the chronograph function for example .
  • the selection member may be placed in a third position which is associated with a third function, and corresponding to the establishment of a third kinematic link between the chronograph driving wheel 2 and the chronograph mobile 3 .
  • the selection member comprises a second flip-flop 40 making it possible to select the third function, and to establish the third observable kinematic link at the figure 4b .
  • the second flip-flop 40 is pivotally mounted on the first flip-flop 30.
  • the second flip-flop 40 comprises a lower plate 41 pivotally mounted on the lower plate 31 of the first flip-flop 30, and an upper plate 42 pivotally mounted on the upper plate 32 of the first flip-flop 30.
  • the lower plate 41 has an orifice 410 configured to receive a pivot of the lower plate 31 of the first latch 30, and the upper plate 42 has an upper pivot 420 configured to fit in a hole 321 of the upper plate 32 of the first
  • the upper pivot 420 and the orifice 410 define the axis of rotation of the second latch 40 relative to the first latch 30.
  • the upper plate 42 is assembled on the lower plate 41 by means of an assembly element 46 integral with the lower plate 41.
  • This assembly element 46 comprises two pins 460 configured to be housed in two corresponding openings 421 on the plate superior 42.
  • the second flip-flop 40 receives the intermediate wheel 430 and the intermediate gear 431, as well as another wheel 440, respectively mounted between the upper plate 42 and the lower plate 41 via an axis 43 and another axis 44. .
