    专利说明:

    The present invention relates to the field of watchmaking. It relates more particularly to a timepiece comprising a mechanism arranged to drive an indicator member in a rotational movement.
    [0002] CH 138 927 describes a movement fixed in the box at a point off center with respect to its center of gravity so that it can oscillate freely under the action of a force. This movement allows a winding of the mainspring.
    [0003] EP 1 664 941 describes a watch movement comprising a visible movable member and providing an animation of the display. The mechanical-type watch movement comprises a frame and, carried by the frame, a finishing gear wheel driven periodically in rotation by a motor member and a part intended to be visible and arranged so as to be driven by an oscillating movement intended to to simulate the movement of a pendulum.
    The object of the present invention is to provide a timepiece with an original display.
    According to the invention, a timepiece comprises a first central axis arranged in the center of a dial space extending to the periphery of an opening in a case of the timepiece, around which first axis is arranged an indexing wheel. The timepiece further comprises at least one arm rotated about the first central axis, a free end of said arm carrying a dial. The dial carries a clock indicating member integral with the dial around a second axis disposed at the center of the dial and offset relative to the first central axis. A pinion, meshing with the fixed indexing wheel, causes the dial to rotate about said second axis when the arm rotates about the first central axis. A mobile rotatably mounted on a central shaft along a third axis, the mobile meshing with gear trains arranged around the second axis of rotation so as to synchronize the dial and the indicator member in normal operation for rotation together about the axis, the dial and the indicator organ rotating in the opposite direction with respect to each other; and to block the dial during the time setting to allow the indicator member to move angularly relative to the dial.
    In one embodiment, the dial, on which is arranged at least one index located towards the periphery, is movable and the arm carrying the dial has a pivot point that goes beyond the dial. The pivot point corresponds to the first central axis of rotation offset from the center of the dial.
    In one embodiment, the mobile allows the indicator organs to rotate in a ratio of 1/12 when setting the time.
    According to this embodiment, the mobile allows the indicator organs to rotate in a ratio of 25/32 in normal operation.
    The dial can rotate about the first central axis of rotation in twenty minutes.
    In one embodiment, the dial is fixed on a support member comprising a ball bearing, rotates in a counterclockwise direction.
    The pinion transmits the rotation information to the dial by rotating it counterclockwise at the same speed as the first central axis.
    The rotatably mounted mobile about the first central axis meshes with a gear train, blocks the dial and allows the timer system to rotate at a different speed compared to the dial when setting the time.
    The pinion is a double pinion.
    According to another embodiment, the mobile rotatably mounted on a central shaft along a third axis is a differential gear comprising wheels rotatably mounted on said central shaft, the differential gear blocking the dial and allowing the system of timer to turn at a different speed compared to the dial when setting the time.
    According to this same embodiment, the pinion is a triple pinion and comprises a first gear for indexing the dial, a second pinion for a time setting and a third gear for a timer train.
    The differential gear rotates synchronized with a timer train in the normal operation of the watch.
    The differential gear blocks the dial and allows the timer system to rotate at a different speed compared to the dial when setting the time.
    The characteristics of the invention will appear more clearly on reading the description of several embodiments given solely by way of example, in no way limiting with reference to the schematic figures, in which:<tb> Fig. 1 <SEP> represents a perspective view of a watch dial carried by an arm;<tb> Fig. 2 <SEP> represents a sectional view of FIG. 1;<tb> Fig. 3 <SEP> represents a perspective view of a watch dial having needles, the dial being carried by an arm;<tb> Fig. 4 <SEP> is a partial sectional view of FIG. 3, an integral wheel disposed about an axis bearing the arm being removed for clarity;<tb> Fig. <SEP> represents a side view of a triple pinion;<tb> Fig. 6 <SEP> represents a side view of a differential gear;<tb> Fig. 7 <SEP> represents a partial view of the components of movement and kinematics during normal operation, that is to say during the rotation of the dial and the time indicator organs;<tb> Fig. 8 <SEP> represents a partial view of the components of movement and kinematics during the blocking of the dial for setting the time; and<tb> Fig. 9 <SEP> represents a perspective view of a watch comprising a mobile dial carried by an arm rotating about the axis of the watch.
    As illustrated in FIGS. 1 and 2, an arm 4 carried by a central axis 5 rotates clockwise around the central axis 5. The arm 4 carries a pinion 6 and a dial assembly composed of an upper part 1 on which are displayed the indexes 16, a lower portion 42 integral with the upper portion 1 and rotated by a wheel 41 which meshes with the pinion 6. A central wheel 20 does not rotate and is therefore fixed. The arm 4 rotates about the central axis 5 and causes the pinion 6 to rotate around the fixed wheel 20 which itself drives the wheel 41. The assembly is dimensioned so that the dial assembly rotates around itself. a second axis 3 offset from the central axis 5 and the dial assembly is rotated about the central axis 5 so that the index 16 remains indexed at noon. A wheel 50 is fixedly mounted on the arm 4 and positioned on the axis 3 so as to mesh with another wheel 52 mounted on a third axis 8 which is placed on the base of the dial, in particular on the lower part 42 of the dial assembly. The rotation of the arm 4 and the dial portion 1, 41, 42 rotates the other wheel 52 in the dial differential. The rotation of the mobile 35, 52, 36 around the third axis 8, causes a roadway 23, a timer 51 and an hour wheel 24.
    Regarding the time setting, it is provided by a gear train comprising the pinion 35 about the third axis 8, the wheel 34 which is secured to the wheel 33 about the second axis 3, and the mobiles 32 and 31. The assembly is sized so that in normal operation the mobile 31, arranged around the central axis 5, does not rotate at all. Indeed, during normal operation of the watch, the mobile 32 rotates around the mobile 31 without rotating. So there is no influence on the functioning of the movement. By cons, at the time of setting, the mobile 31 rotates to mesh all gear 32, 33, 34, 35 setting time. The wheel 52 is lanterned on the axis 8 by means of a foil.
    As illustrated in FIG. 7, a wristwatch comprises, inside the watch case, four modules carried by a carriage with four arms 4 which drive each of the modules in a permanent circular movement on the periphery of the watch case. A complete rotation takes place in twenty minutes. The modules are a mobile dial 1, a whirlwind, and two other decorative elements namely a land and a moon.
    On the top of the watch, a sapphire crystal offers a top view of the four modules. The watch case further comprises on its middle band 13 four openings 14 arranged between four horns 15, said openings 14 letting appear the internal modules to the watch case.
    In contrast to the whirlpool module, the perforated dial 1 hours and minutes has a perfect readability. Moreover, while it is rotated by a central carriage, the dial 1 keeps the same orientation, the index 16 disposed at the top of the dial 1 remains at the top of the dial 1. FIG. 3 illustrates the dial module 1 on which hands 2 display 10:10 and the index 16 with the value XII is at the top of the dial 1.
    As illustrated in FIG. 4, the movement comprises a pinion 6 with triple function and a double differential gear 7 to not only rotate the hands 2 and the dial 1 but also to index the dial 1.
    Indeed, the triple pinion 6 comprises a first set of teeth 17 to ensure rotation and indexing of the dial 1, a second toothing 18 to ensure a time setting and a third set of teeth 19 to mesh with a timer gear (see Fig. 5).
    The differential gear 7 illustrated in FIG. 6 having a central shaft 8 on which are rotatably mounted the first second and third wheels 9, 10, 11 each of which is provided with a toothing arranged to mesh with the wheels of the movement so as to synchronize the dial 1. The first wheel 9 ensures the time setting, the second wheel 10 ensures a blocking of the dial 1 and the third wheel 11 ensures the time setting.
    The differential gear 7 thus transmits rotation information to the dial 1 by rotating it counterclockwise at the same speed as the central axis 5 in this way the dial 1 gives the impression of being blocked.
    The needles 2, thanks to information pinion 6 triple function remain indexed with the dial 1 and turn synchronized with the latter counterclockwise.
    In normal operation, as shown in FIG. 7, the dual differential 7 turns synchronized with the timer. Indeed, the pinions 17 and 19 of the triple pinion 6, are integral and rotate, causing the dial 1 in rotation and the hands 3, the dial 1 and the needles 3 being indexed with respect to each other.
    At the time of setting the time, as shown in FIG. 8, the wheel 10 of the double differential 7 blocks the dial 1 and allows the timer system to rotate at a different speed relative to the dial 1.
    In the illustrated example, the needles 2 rotate with a rotational ratio (1/12) during the time setting while in normal operation they rotate with a rotational ratio (25/32).
    This description and these ratios are given only as an example and other values are possible.
