Definitions

  • the present invention relates to a watch device, or analogous, of a new type.
  • a watch, or the like, of the needle killer includes generally a clockwork movement leading in rotation two coaxial pivots, an hour pivot bearing a hand hours, and a minute pivot with a hand minutes, the latter axially crossing said pivot of hours which is tubular.
  • the watch face or the like is traditionally divided into twelve equal parts each representing one hour, and the angular speed of rotation of the hour pivot is, by a reduction effect, twelve times smaller than that of the minute pivot, so that when the hand hours runs through one of said parts, i.e. an hour, the minute hand runs across the entire dial.
  • the object of the present invention is to propose a device for shows, or the like, a needle killer, the mechanism of which provides an original aesthetic result.
  • the watch device, or the like, object of the present invention comprises a clockwork movement resulting in different speeds two coaxial pivots, namely on the one hand an hour pivot to which a hand is attached marking the hours on a dial, and on the other hand a pivot of the minutes, and it is essentially characterized in that it has a dial graduated in minutes which is in orbit around of said pivots by being linked to said hour hand by through an axis not coaxial with said pivots, said axis, which carries a minute hand running through said dial of minutes, being rotated in an epicyclic movement via overdrive gears, and in that said minute dial is animated in rotation, at a speed angular equal to that of said hour hand and in the opposite direction to that of the said minute hand, by via geared gears connecting it to said pivot minutes.
  • a gear wheel coaxial with the axis which carries the minute hand without being linked in rotation to this one is fixedly fixed to the minute dial and meshes with a pinion integral with the minutes pivot, the transmission ratio of said pinion and said toothed wheel being such that said minute dial is animated by a reverse rotation movement from that of said needle minutes and angular speed equal to that of the hours, while a second pinion is carried by said axis and which, under the effect of the pivoting of the hour hand, rolls without sliding on a second fixed gear coaxial with hour and minute pivots, transmission ratio between said second pinion and said second gear being such that said minute hand makes a full turn when the hour hand travels an hour on the dial hours.
  • the hour dial is divided into twelve hours, the pinion carried by the minutes pivot being of a diameter twelve times smaller than the diameter of the gear secured to the minute dial, while the pinion carried by the axis carrying the minute hand is twelve in diameter times smaller than the diameter of the fixed gear.
  • the watch device, or the like, object of the present invention comprises a clockwork movement driving at different speeds two coaxial pivots, at to know on the one hand a pivot of the hours to which is united a hand marking the hours on a dial, and on the other hand a pivot of the minutes, and it is essentially characterized by what it has a dial graduated in minutes which is in orbit around said pivots by being linked to said hour hand via a pivot not linked in rotation to said audit dial, which carries the minute hand, offset from the center to the said hour and minute pivots, and driven to the same angular speed by means of pinions, and in that said pivot of the minutes drives said minute dial into opposite direction and at an angular speed equal to that of the hour hand via pinions multiplied.
  • the hour dial is divided into n hours, and the minute dial is attached to a pinion connected to a pinion carried by the minutes pivot by through 2p double gears, the numbers of teeth said pinion and said double pinions being such that the angular speed of said minute dial is (n - 1) times smaller than the angular speed of said minutes pivot.
  • the watch device, or the like, according to the invention thus has an hour hand with a minute dial offset from the pivot axis of said hour hand, and traversed by a hand of minutes, said minute dial retaining the same orientation, i.e. that of the hours dial, describing the periphery of the latter on said hour hand.
  • a first mode for producing the watch device according to the invention has an hour dial 1 divided into twelve equal parts, as well as a 10 hour hand running through the dial of the hours 1.
  • Hour hand 1 has a divided minute dial 2 in sixty equal parts, and traversed by a needle of 20 minutes.
  • a device according to the invention includes a mechanism clockwork 3 known per se, shown only on the Figure 3, animating on the one hand a pivot of the hours 11 and a minute pivot 21, the latter passing axially in the 11 o'clock pivot which is tubular.
  • the minutes dial 2 is crossed by an axis 22 which crosses also the hour hand 10 parallel to the pivots 11 and 21 and at a certain distance from them, the axis 22 being in free rotation in the minute dial 2 and the hand 10 hours.
  • the minute hand 20 is secured to one of the ends of axis 22 while the other end carries a pinion 23 which meshes on a toothed wheel 30, integral fixing the clockwork movement, and coaxial with the pivots 11 and 21.
  • the diameter of the pinion 23 is twelve times smaller than the diameter of the wheel toothed 30, while the diameter of the pinion 25 is twelve times smaller than that of the gear 24.
  • the clockwork movement 3 rotates the hour pivot 11 clockwise H, shown on Figures 1 and 2, which causes the movement in the direction H, and concentrically with the pivot of the hours 11, of the axis 22, whose pinion 23 rolls on the toothed wheel 30 which causes the rotation of the axis 22 and therefore of the minute hand 20, the gear ratio of the pinion 23 and the toothed wheel 30 making the 20 minute hand circle complete when the 10 hour hand describes a twelfth of the hour dial 1.
  • the clockwork movement rotates the minute pivot 21 whose angular speed is conventionally twelve times higher than that of the 11 hour pivot.
  • the pinion 25 thus drives the toothed wheel 24, but in the anti-clockwise A, and, due to the diameter ratio, to an angular speed twelve times lower, that is to say that of 11 o'clock pivot, so that the 2 minute dial remains always oriented in the same way with respect to the hour dial 1, although it is moved by the hour hand 10.
  • the hour hand 10 has a cylindrical cavity 12, concentric with the axis 22, which houses the pinion 25, the toothed wheel 24 and the minute dial 2, so on the one hand that this last is flush with the surface of the hour hand 1, and on the other hand that the whole mechanism remains invisible.
  • the pivot 4 carries a double pinion 40 consisting of a wheel 41 of large diameter meshing with a pinion 26 secured to the pivot minutes 21, and a wheel 42 of smaller diameter, while that the pivot 5 carries a double pinion 50 consisting of a wheel of large diameter 51 which meshes with the wheel 42, and of a wheel 52 of smaller diameter on which a wheel meshes 60 in free rotation on the pivot 6 and to which is secured the minute dial 2.
  • the pivot 7 carries a pinion 70 which meshes with the pinion 26, and on which meshes a pinion 61 carried integrally by pivot 6 at the end of which is fixed the minute hand, not shown, the pinions 26 and 61 being identical, thus allowing the displacement of the minute hand at an angular speed equal to that of the minute pivot 21.
  • the ratios of the teeth between the different pinions and wheel are such that the angular speed of the dial of minutes 2 is, counterclockwise A, (n - 1) times lower than the angular speed of the minutes pivot 21, n being the black of hours worn on the hour dial.
  • the pinion 26 and 61, as well as the wheels 42 and 52 comprise each twelve teeth, while the wheels 41 and 51 have them each twenty-four, and that the pinion 60 has 33, the number of teeth of the pinion 70 being indifferent.
  • This second embodiment has the advantage over first, to allow the establishment of a needle awakening, indeed in the first embodiment, the presence of two linked coaxial axes prevents the displacement of a additional needle.
  • the device according to the invention is made from a movement classic watchmaking requiring no modification.
