    Description: The present invention relates to a display mechanism for equipping a timepiece. In particular, the present invention relates to a display mechanism for displaying a quantity (hour, minute, power reserve, date, etc.) using a plurality of display members.
    [0002] EP 3070538 discloses such a display in which a plurality of display members are simultaneously driven at different speeds. A single probe works with a cam and the display members have different gear ratios with the probe.
    EP 0 389 739 and EP 1 102 134 describe a display comprising a plurality of display members each connected by a gear to a corresponding probe. The probes are controlled by a single cam for the training of the display members.
    Finally in the document CH 704 696, the display members are also each connected by a gear to a corresponding probe but each sensor cooperates with a dedicated cam.
    The object of the present invention is to provide a display mechanism proposing an alternative construction to those above and allowing an original display and versatile.
    To do this, the present invention relates to a display mechanism for equipping a timepiece and comprising a plurality of display members to be driven sequentially to display information, said bodies each of which is associated with a corresponding probe, each probe being arranged to cooperate with control means, characterized in that at least two probes are integral with their respective display member.
    The present invention also relates to a timepiece according to claim 11.
    The accompanying figures schematically illustrate an embodiment of the display mechanism according to the present invention.
    Fig. 1 is a perspective view of a display mechanism according to the invention for displaying the movement reserve of a movement of a timepiece.
    Fig. 2 is a side view of the mechanism of FIG. 1.
    Figs. 3a to 3e are top views of the display mechanism of FIG. 1 in several different positions.
    Figs. 4a to 4e correspond to figs. 3a to 3e and illustrate the integration of the display mechanism in a timepiece movement.
    Figs. 5a to 5e are perspective views of FIGS. 4a to 4e.
    The display mechanism according to the invention is intended to equip a timepiece. In the illustrated embodiment, the display mechanism according to the invention is a mechanism for displaying the state of the power reserve of the driving member (a barrel for example) of the movement of the timepiece .
    The display mechanism comprises a plurality of display members intended to be sequentially driven for displaying the information to be displayed (power reserve for example). In the illustrated embodiment, these display members are in the form of four flaps 1, 2, 3, 4 arranged in a fan-shaped manner so that, when fully extended (Fig. 3a, 4a, 5a), they indicate a reserve of full, while fully folded (Fig. 3e, 4th, 5th) indicate an empty or almost empty power reserve.
    Each louver 1,2,3,4 is pivoted on the movement of the timepiece at a corresponding point. The shutters 1, 2, 3, 4 are pivoted independently of each other. According to the invention, each shutter 1, 2, 3, 4 is associated with a probe 5, 6, 7, 8 corresponding and at least two flaps are integral with their probe. In this embodiment, three flaps 2, 3, 4 are integral with their respective probe 6, 7, 8 having come in one piece, monoblock, with it. Alternatively, the probe 6, 7, 8 could be an insert attached to its display member 2, 3, 4. As for the first component 1, its sensor 5 is formed of a return lever 50 pivoted freely on the movement of the timepiece and comprising a first pin 51 for cooperating with a slot 100 of the flap 1 for their articulation.
    According to the invention, each probe 5,6, 7, 8 cooperates with control means for the sequential drive flaps 1, 2, 3, 4. In the present embodiment, the control means comprise cams and each feeler 5, 6, 7, 8 cooperates with a corresponding cam 9, 10, 11, 12. In the case of the probe 5 of the first flap 1, it further comprises a second pin 52 intended to cooperate with its corresponding cam 9. Alternatively, two or more probes can cooperate with the same cam.
    The cams 9, 10, 11, 12 are arranged to drive the flaps 1,2, 3, 4 sequentially for displaying the information to be displayed, here the power reserve. Preferably, the cams 9, 10, 11, 12 are distinct and coaxial, each driven on a shaft 20. Alternatively, the cams 9, 10, 11, 12 could be replaced by a single multilevel cam also driven on the shaft 20. In this variant, the cam can comprise as many levels as display members for their independent drive via their respective probe or several probes can cooperate with the same level of the cam.
    Elastic means are used to press each of the feelers 5, 6, 7, 8 in contact with their respective cam 9, 10, 11, 12. In the present embodiment, each feeler 5, 6, 7, 8 has its own corresponding return spring 13, 14, 15, 16.
    The shaft 20 carrying the cams 9, 10, 11, 12 is integral with a pinion 21 by which the information to be displayed, or in the illustrated embodiment, the state of the power reserve . This information is transmitted by an unillustrated gear from the drive member (for example barrel) of the movement of the timepiece.
    Figs. 3a-3e, 4a-4e and 5a-5a illustrate the operation of the display mechanism of the power reserve. In figs. 3a to 3e, the mechanism is presented alone, while in figs. 4a to 5e, the mechanism is illustrated integrated in the movement of a timepiece.
    Figs. 3a, 4a and 5a illustrate a full power reserve (all the shutters 1, 2, 3, 4 are deployed) while FIGS. 3rd, 4th and 5th illustrate a power reserve exhausted (or almost exhausted, all the shutters 1, 2, 3, 4 are folded). Figs. 3b, 3c, 3d, 4b, 4c, 4d and 5b, 5c, 5d illustrate the mechanism in intermediate positions between these two extremes.
    When the drive member of the movement operates and starts its energy reserve, it rotates via a not shown gear pinion 21. This in turn drives in rotation the shaft 20 and the cams 9, 10 , 11,12. The cams 9, 10, 11, 12 then sequentially drive the flaps 1, 2, 3, 4 via their feeler 5, 6, 7, 8 each pressed against said cams by their return spring 13, 14, 15, 16 .
    Preferably, the cams 9, 10, 11, 12 are shaped and arranged on the shaft 20 so that at any time, only one flap 1, 2, 3, 4 at a time is moved. Alternatively, the cams 9, 10, 11, 12 could be indexed so that several flaps 1, 2, 3, 4 move simultaneously.
    Thus, as the drive member exhausts the first quarter of its power reserve, the fourth component 4 moves and pivots from its deployed position (FIGS 3a, 4a, 5a) to fall back partially under the third flap neighbor 3 and / or partly under a bridge or part of the movement dial (see Fig. 4b and 5b). The other shutters 1,2, 3 remain motionless.
    When the motor organ starts the second quarter of its power reserve, it is the turn of the third flap 3 to pivot to fall partly under the second flap neighbor 2 and / or partly under a bridge or a part of the movement dial (see Fig. 4c and 5c). The other shutters 1,2, 4 remain motionless.
    When the motor unit starts the third quarter of its power reserve, it is the turn of the second flap 2 to pivot to fall partly under the first flap neighbor 1 and / or partly under a bridge or a part of the movement dial (see Fig. 4d and 5d). The other shutters 1,3, 4 remain motionless.
    Finally, when the drive member starts the last quarter of its power reserve, the first flap 1 pivots to fall back under a bridge or part of the dial of the movement (see Fig. 4e and 5e). The other shutters 2,3, 4 remain motionless.
    The above sequence occurs in the opposite direction when the drive member is raised until the power reserve is full again. This is particularly possible because the mechanism is arranged so that the shaft 20 and the cams 9, 10, 11,12 performs a rotation less than a full revolution whatever the direction of rotation. In particular, in the illustrated embodiment, the mechanism comprises an abutment for actuating a friction at the shaft 20 preventing it from rotating further when the drive member of the movement is fully armed. Thus, raising the motor member to the maximum or completely emptying the power reserve of said member corresponds each time to a rotation less than one revolution of the shaft 20 and the cams 9, 10, 11, 12.
    Thus a display mechanism is realized comprising a multitude of display members driven sequentially and to display the same size for an original and aesthetic effect. Needles or any other suitable display member may replace the flaps described above. The cams forming the control means may be replaced by one or more appropriate control members, several probes being able to cooperate with the same control member. Similarly, the mechanism can be used to display other information than the power reserve as a time indication (hour, minute), a date ...
    In addition, the display mechanism according to the invention is very simple since limiting gearing demultiplicatives between the feelers and their display member. It is nevertheless very versatile since each display member has its own probe allowing a large variation in the sequence of displacement of the display members. According to the arrangement of the control means, the mechanism further allows to have only one display member in motion at a time, as in the illustrated embodiment.
