Definitions

  • the invention relates to a device for disengagement in a workpiece gear train clockwork, this train operating a minute wheel at from a drive member and comprising a plurality of mobiles arranged in a chain and meshing one on the other, this chain including a detachable mobile at least one of the other mobiles under the action of a lever controlled by a time-setting rod, defining two positions, a first position in which is maintained the chain of meshed mobiles and a second position in which said chain is interrupted and stops the minute wheel, the mobile detachable undergoing, when activated, a translational movement relative to other mobiles, the axes around which all the mobiles revolve remaining substantially parallel to each other.
  • the declutching device is also arranged between a drive member and a wheel of the minutes. It is a detachable mobile from the wheel of minutes, this mobile being known as a wheel medium, but actually comprising a wheel and a gable having a common tree.
  • the wheel is engaged with a second gear in the center, while the gear is engaged with the minute wheel.
  • One of the pivots of this mobile which we will call medium, turns in a borehole practiced in a bridge, while the other pivot turns in a borehole made in a lever controlled by a time-setting rod.
  • the shaft of the average mobile tilts so that its pinion comes out of the teeth of the wheel minutes.
  • the time display of the time and minute is thus stopped, the needles can then be set by the stem via the timer.
  • This declutching device has the drawback of increasing the thickness of the timepiece, since it is understood that there must be room for the mean wheel in the inclined state.
  • the present invention in addition to satisfying the preliminary description given in the first paragraph of this description is remarkable in that the lever is not integral with the rod and includes means for solidarity reminder of the latter, allowing return from the second position to the first.
  • FIGs 1 to 4 show how the device for setting the time of the timepiece.
  • This device comprises a time-setting rod 8.
  • This rod is capped at one of its ends by a crown 28 which allows the rod to be manipulated with the fingers.
  • the rod can be placed in a first neutral position pressed 20 as shown on Figures 1 and 2. In this neutral position, the rod has no action on room timer 24 watchmaking. If it is rotated, it therefore turns in a vacuum. From this position pressed, the rod 8 can be pulled to occupy the position illustrated in Figures 3 and 4. In this pulled position 21, the rod 8 cooperates with a mobile timer 24 comprising a wheel 29 and a pinion 30 secured to a shaft 35 to allow time setting 23 and 22 hour hands.
  • a mobile timer 24 comprising a wheel 29 and a pinion 30 secured to a shaft 35 to allow time setting 23 and 22 hour hands.
  • Figures 2 and 4 show particularly well that the end of the rod 8 opposite to that capped by the crown 28 is arranged to rest on a peripheral zone 32 of the timer wheel 29 when the rod 8 is pulled out second position 21. At this time, the timer wheel 29 can be frictionally driven by the rod 8 when this rod is actuated in rotation.
  • Figures 1 to 4 show such a device clutch inserted in a gear train 1 piece clockwork, this train driving a minute wheel 2 from a drive member 3.
  • the figures show that the gear train 1 comprises a plurality of mobiles 4, 5 and 6 arranged in a chain and meshing one on the other.
  • This chain has a detachable mobile 5 of at least one of the other mobiles (of mobile 6 in the execution illustrated by the figures) under the action of a lever 7 controlled by the time setting rod 8 to interrupt the chain and stop the minute wheel 2.
  • Figures 2 and 4 show the detachable mobile 5 respectively attached and detached from the gear train 1. It is important to note here that the detachable mobile 5 undergoes, when it is actuated by lever 7, a movement of translation compared to other mobiles 4 and 6. In indeed, the axes around which all the mobiles revolve 4 to 6 remain substantially parallel to each other.
  • Figures 1 to 4 show that the timepiece is provided with a rod 8 capped with a crown 28 which facilitates handling of the rod.
  • This rod can be disposed in a first depressed position 20 ( Figures 1 and 2) or in a second pulled position 21 ( Figures 3 and 4).
  • the rod 8 is guided in a plate 40 and has a first groove 41 in which engages a spring of positioning 42 when this rod is first depressed position, and a second groove 43 in which engages this same spring 42 when the rod is in second position pulled.
  • Gorges 41 and 43 are separated by a bead 44.
  • the other end of the rod 8, that opposite to the crown 28, has a pommel 31.
  • the reference 24 designates the timer mobile which comprises a shaft 35, a wheel 29 and a pinion 30.
  • the timer mobile which comprises a shaft 35, a wheel 29 and a pinion 30.
  • annular bead 32 on which comes lean on the knob 31 of the rod 8 when this rod is found in second position pulled (figure 4). So in this situation drawn, when the rod 8 is actuated in rotation, it causes the bead 32 by friction and with him all the timer mobile 24.
  • timer 29 Like the wheel of timer 29 is engaged with a carriageway 45 which carries, at the same time as a timed wheel 2, a hand minute 22 and as the timer pinion 30 is engaged with a cannon wheel 33 carrying an hour hand 23, we understand that when the rod 8 is actuated in rotation, we drive the timer wheels 29 and pinion 30 which drive in turn and respectively the needles minute 22 and hour 23, which allows their updating time.
  • the good contact between pommel and bead is not limited to the example just described.
  • the return spring could be controlled by the rod at when it is drawn. This spring would then support to prevent it from lifting, the wheel always staying in one plane.
  • the time setting device which has just been described differs from document EP-B-0 261 243 cited more high, first by the fact that it has no gable singing, then by the fact that it does not require a extreme precision to drive two parts by friction cooperating with each other.
  • the declutching device has a mobile 5 detachable from a gear train 1 comprising a plurality of mobiles 4 to 6 arranged in chains, this mobile 5 undergoing, when actuated by a lever 7 controlled by the time setting rod 8, a movement of translation compared to other mobiles 4 and 6, axes of all mobiles remaining substantially parallel between them.
  • the gear train 1 in question here connects a motor 3 mu by hourly pulses at one wheel minute 2 which carries the minute hand 22.
  • the motor 3 is preferably of the step-by-step type comprising a stator 46, a core 47 surrounded by a coil 48 and a rotor magnetized 10 whose shaft carries a pinion 9.
  • the gear train 1 first comprises an intermediate mobile 4 engaged with the pinion 9 carried by the rotor 10 of the motor 3, then the detachable mobile 5 engaged with said mobile intermediate 4 and a medium mobile 6 engaged with said detachable mobile 5, this medium mobile being engaged with the minute wheel 2.
  • the intermediate mobile 4 comprises a wheel 49 meshing with the pinion 9 of the rotor 10 and a pinion 12 meshing with a wheel 11 carried by the mobile detachable 5.
  • the detachable mobile further includes a pinion 13 in engagement with a medium wheel 14 carried by the medium mobile 6, which medium mobile 6 still carries a pinion 50 which meshes with the minute wheel 2.
  • the detachable mobile 5 is pivotally mounted on a stud 15 which is integral lever 7 controlled by rod 8.
  • lever 7 controlled by the rod 8 is a blade 16 pivotally mounted on the axis around which the intermediate mobile 4 turns.
  • the end 17 of this lever 7 is rolled up in the form of nose to cooperate with rod 8 or more exactly with the knob 31 of this rod.
  • the other end 18 of this same lever 7 has a thinned part to form a elastic portion which rests on a nipple 19.
  • train 1 comprises a detachable mobile of at least one of the other mobiles, but we will understand that another provision could cause the detachable mobile to detach from each of the neighboring mobiles.
  • the hour 23 and minute 22 hands are now stopped, which allows the rod 8 to cooperate with the mobile timer to set the time needles.
