    Description
    Technical Field [0001] The present invention relates to the field of watchmaking. More particularly, it relates to a timepiece comprising a chronograph mechanism and an additional display system.
    STATE OF THE ART [0002] Mechanisms are known that make it possible to carry out several measurements of a timed time, for example with systems of the catch-up type or stop seconds. Several indicators are then associated with a chronograph mechanism, the different indicators can be stopped independently, following a manual action of a user.
    There are also known regatta watches, in which there is a countdown, which can be programmed, and at the end of which the chronometric measurement starts. In general, it is the chronograph that continues to operate, with the switching on of an inverter at the 0 countdown.
    The present invention aims to provide another type of measurement, particularly useful in certain sports applications, in which one can display a timed time, and also a second measured time.
    Disclosure of the invention [0005] More specifically, the invention relates to a timepiece as defined in the claims.
    BRIEF DESCRIPTION OF THE DRAWINGS Further details of the invention will appear more clearly on reading the description which follows, given with reference to the appended drawing in which FIGS. 1 to 4 show a particular embodiment of the invention, in different operating positions.
    Embodiment of the Invention [0007] Thus, the invention relates to a timepiece comprising: a chronograph mechanism for measuring and displaying a timed time; an additional display system 12 for displaying a second timepiece; measured time, said additional display system 12 being adjustable according to a parameter, - means for adjusting said parameter.
    According to the invention, the additional display system 12 is arranged to be driven automatically by the chronograph mechanism 10 according to the parameter, in the continuity of a first period of operation of the chronograph mechanism 10 determining the switching on the display system.
    In the embodiment which will be described hereinafter with reference to the figures, the additional display system 12 is a countdown timer and the parameter is the duration of the second measured time.
    Such an embodiment makes it possible for example to make a watch intended to be used to measure the duration of a sports match, for example a football match, in which one wishes to have a measure of the stops of the game. will understand below, the timepiece according to the described embodiment allows to manually adjust the number of minutes of play stopped indicated by the assistant referee at the end of halftime. At the end of regulation time, the countdown is automatically triggered, while the chronograph continues to work, decrementing the additional time while measuring the entire duration of the half-time.
    In the following description, the elements relating to the chronograph mechanism 10 are not described in detail, and only the elements useful for understanding the invention have been shown. The present invention can be adapted to any type of chronograph and the person skilled in the art knows them well, so that his general knowledge allow him to fully understand the invention and to implement it, without specific description of the chronograph.
    In FIG. 1, there is shown the timepiece according to the preferred embodiment, in its rest position, while there is no measurement in progress. There is thus a central counter, which is a second counter 14 of the chronograph mechanism 10. This counter is driven at the request by a user, when he operates the chronograph (START). There is also shown a minute counter 16 of the chronograph. These two counters indicate 0, in the position of FIG. 1.
    In this figure, there is also shown an additional counter, which is part of the additional display system 12. In accordance with the example, this additional counter makes it possible to indicate the additional time of a half-time, in the kind of a football match.
    Technically, in the proposed embodiment, the timepiece comprises a control cam 18, integral with the minute counter. Indeed, for a football game, the duration of a half-time is in minutes, and it is this half-time that will trigger the countdown. Thus, the control cam 18 comprises two different levels of radii, a first level occupying substantially 270 degrees, and a second level occupying substantially 90 °. In the example, the second level has a radius smaller than the first level.
    The timepiece further comprises a trigger rocker 20 cooperating with the control cam 18. A spring 21 is arranged to maintain a probe 22 of the trigger rocker 20 bearing against the periphery of the control cam 18 The rocker 20 and the cam 18 are arranged so that the probe 22 is located at the passage between the first level and the second level. Thus, the probe 22 is positioned on the first level during the 45 minutes of a half-time, defining a first position of the trigger rocker 20, and falls on the second level at the end of the half-time, defining a second position of said trigger rocker 20.
    The timepiece comprises a movable finger 24, arranged on a wheel secured to a counter of the chronograph mechanism 10, said finger 24 being adapted to cooperate with a display mobile of the additional display system 12, in this case the additional meter. In the example, the finger 24 is arranged on a wheel 26 secured to the seconds counter 14. The finger 24 is resiliently disposed on the wheel 26. At rest, the finger 24 occupies a position in which it protrudes from the wheel 26, in the example, beyond its perimeter. He can then cooperate with the mobile display. One could also consider a position beyond or below the plane of the wheel.
    The finger 24 is located at the end of an elastic strip 28, cut in the wheel and has a projection lug, not visible, with which the trigger rocker 20 can cooperate. The finger 24 also has a spout, arranged to cooperate with the display mobile. When actuated by the trigger rocker 20, the finger 24 is returned to the space in which the wheel 26 fits, without exceeding its circular perimeter, that is to say the perimeter of the wheel 26 by ignoring the cut. Thus, the finger 24 does not cross the path of the display mobile.
    When the trigger rocker 20 is in its first position, it acts on the finger 24 to actuate and bring it out of the display of the mobile. When the trigger rocker 20 is in its second position, the chronograph mechanism 10 is connected to the additional display system 12, leaving the finger 24 occupy its rest position, in which it crosses the path of the display mobile. Thus, the finger 24 can cooperate with the mobile display once a minute, each turn of the seconds counter, thus allowing to count the minutes of the additional time.
    To adjust the parameter, according to the example, the number of minutes of the additional time, the mobile display can be moved by a lever 30, operable by a user, by means of a push for example. A jumper 32 positions the mobile display and provides training in steps equivalent to one minute of display.
    Thus, when a half-time begins, the user starts the chronograph. The seconds counters 14 and minutes 16 are driven. Lafig. 2 illustrates the position at 14minutes and 55 seconds of play. The trigger rocker 20 is in its first position and the finger 24 does not actuate the display unit, which is always in position 0, since no stop of game has been announced.
    Towards the end of the half-time, the number of minutes of stopping play is announced and the user sets the number of minutes to count down, as shown in FIG. 3, where two minutes have been defined. The elapsed game time is 44 minutes 55 seconds. The trigger rocker 20 is always in its rest position and the finger 24 does not actuate the display mobile.
    At 45 minutes, that is to say after a predetermined duration, corresponding to a half-time, and corresponding to the angle occupied by the first level of the control cam 18, the additional display system 12 starts automatically, the trigger rocker 20 falling on the second level of the cam 18.
    FIG. 4 represents the situation at 45 minutes and 59 seconds. The probe 22 of the control rocker 20 is on the second level and the rocker is in its second position. The finger 24 is in its rest position and protrudes from the wheel. It is positioned to cooperate with the mobile display and decrement the countdown of the minutes of play stoppage. The chronograph still works and the counters indicate the total time of play.
    When the game stops are over, we can provide an automatic chronograph stop device, arranged to stop the chronograph at the end of the countdown. Automatically, the additional display system 12 is also stopped, since it is driven by the chronograph mechanism 10.
    One can also provide a ringing device, arranged to emit a sound signal at the end of the countdown. This sound may sound to warn the user that he must stop the chronograph if there is no automatic stop.
    The mobile display could include a truncated tooth, allowing a stop countdown of the countdown to a desired position, regardless of the continuity of operation of the chronograph.
    In a variant not shown, the parameter is the moment of triggering the drive of the display system. One could thus obtain a timepiece in which the user can define a reference time. The additional display system 12 starts for a predefined time window around the reference time. Thus, for example, a display of seconds starts, for example 10 seconds before the reference time and 10 seconds after (the reference time may not be in the middle of the window). One can thus have a playful function, which allows to have a precise measurement around a reference time. Such a function can be

    obtained by adapting a mechanism as described above, in which the control cam 18 can be angularly positioned relative to the counter on which it is mounted, or relative to another gear driven by the chronograph. It is thus possible to determine the moment when the additional display system 12 is switched on. At the end of the scheduled window, the chronograph mechanism 10 may be stopped automatically or it may continue. It will provide a reset display of the display of the additional display system 12, coupled to the reset of the chronograph. A setting of the triggering time can also be combined with the setting of the duration, as proposed above. Such a setting makes it possible to adapt the timepiece to shorter half-times for another sport or different categories. It can thus be proposed to have a control cam 18 on two superimposed boards, and one of which can be moved angularly with respect to the other. This relative displacement makes it possible to adjust the angular distribution of the first level and second level zones, thus determining the counting time of the countdown. The present description has been given by way of non-limiting example of the invention and the skilled person can imagine various alternatives, the basis of this teaching, without departing from the scope of protection determined by the scope of claims. claims
