Definitions

  • the present invention relates to a device for time setting in a timepiece, this device comprising a time-setting rod capable of being arranged, using a crown covering one of its ends, in a first neutral position pushed in or in at least a second pulled position for which the rod cooperates with a timer mobile comprising a wheel and a pinion to allow time setting hour and minute hands.
  • the time setting device in addition to meeting the description preliminary given in the first paragraph of this description, is remarkable in that the other end of the rod is arranged to rest on an area timer wheel device when the rod is pulled in second position, the timer wheel being then likely to be driven by friction when the rod is rotated.
  • Figures 1 to 4 show how the device for setting the time of the timepiece.
  • This device includes 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 arranged in a first neutral position pressed 20 as shown on the Figures 1 and 2. In this neutral position, the rod is without action on the timer 24 of the timepiece. If it is rotated, it therefore rotates in the void. From this depressed position, the rod 8 can be pulled out to occupy the position illustrated by Figures 3 and 4. In this pulled position 21, the rod 8 cooperates with a timer mobile 24 comprising a wheel 29 and a pinion 30 secured to a shaft 35 to allow setting the hour 23 and minute hands 22.
  • 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 an area device 32 of the timer wheel 29 when the rod 8 is pulled in second position 21. At this time, the timer 29 can be frictionally driven by the rod 8 when this rod is actuated in rotation.
  • Figures 1 to 4 show such a device declutching inserted in a gear train 1 of part clockwork, this train driving a wheel of minutes 2 to 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 includes a detachable mobile 5 of at least one of the other mobiles (from 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.
  • 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 (FIGS. 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 the second pulled position ( 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, together with a minute 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 setting time.
  • 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 by friction two pieces 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 comprises 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.
