Definitions

  • the present invention relates to a timepiece movement comprising, on the one hand, timekeeping means formed by engagement mobiles capable of providing time information, and on the other hand, at least one control member, such as a rod, intended to act on these horometric means.
  • the invention relates to a timepiece movement of the above-mentioned type, provided with means intended to allow the rod to be guided.
  • control rod In conventional watchmaking movements, the control rod is generally guided via its free end which is housed in a guide orifice formed in a plate of the movement.
  • the guide hole is formed by a lateral hole made directly in the plate.
  • This drilling is expensive to perform because it requires several handling operations and a long and necessarily very precise machining job.
  • the present invention therefore aims to overcome the drawbacks of the prior art by providing a movement comprising means for guiding the rod, which are easily achievable and at a very low cost.
  • the subject of the invention is a timepiece movement comprising horometric means capable of providing time information and at least one control member intended to act on these means, this control member being guided axially and / or in rotation by means of guide means, characterized in that said guide means consist of three guide pieces mounted and held one on the other sandwiched to form between them a housing in which said control member is freely received.
  • the movement according to the invention which is represented by the general reference M, comprises a plate 1, a center bridge 2 and a gear train bridge 4 which support horometric means H capable of providing a hourly information, such as the hour, minutes, and in this example the second.
  • the horometric means H comprise a certain number of mobiles formed respectively by a timer mobile 6, a second gear 8 and a timer wheel 10.
  • the timer mobile 6 includes an hour cannon 12 carrying a wheel 14 meshing with the timer wheel 10 which is mounted directly on a lug 16 formed on the plate 1.
  • the timer mobile 6 further comprises a carriageway 18 which supports the 12 hour cannon and which comprises, driven thereon, on the one hand, a minute pinion 20 meshing with the timer wheel 10, and on the other hand, a minute wheel 22 meshing with the second gear 8.
  • the roadway 18 is mounted movable in rotation on a fixed barrel 24 whose base 26 is driven into the center bridge 2.
  • the center bridge 2 therefore provides support for the hour cannon 12 and the carriageway 18 via the fixed cannon 24.
  • the mobile 6 also comprises a seconds axis 28 which is also supported by the center bridge 2 while being housed in rotation in the fixed barrel 24.
  • the seconds axis 28 is also guided by the gear train 4 in which it is rotatably mounted.
  • the seconds axis 28 comprises, driven thereon, a seconds pinion 30 meshing with the second gear 8, and a drive wheel 32 engaged with the motor means of the movement M, not shown.
  • the movement M according to the invention further comprises a time-setting rod 34 forming a control member intended to act on the timekeeping means H in a conventional manner.
  • this rod 34 is also conventionally mounted a sliding pinion 36 capable of meshing with the timer wheel 10 which here forms the time setting reference.
  • the rod 34 is shaped to be able to move axially along a geometric axis A as well as in rotation about this axis.
  • the invention is not limited to this type of control member and can be applied to control members having only either an axial displacement or a rotation movement.
  • the rod 34 has a free end E which is guided by the plate 1, by the center bridge 2 and by the gear train bridge 4.
  • the center bridge 2 which forms an intermediate piece between the other two parts 1 and 4, has a through groove 38 oriented along the geometric control axis A and in which is housed and can move the free end E.
  • This groove 38 provides lateral guidance of the free end E which is moreover trapped on either side by the gear train 4 and by the plate 1.
  • the plate 1 and the gear train 4 respectively comprise bosses 40 and 42 which protrude into the groove 38.
  • the gear train 4 is constituted by a stamped part on which three feet 44, 46 and 48 are formed.
  • the feet 44 and 46 rest directly on the center bridge 2 and are fixedly held thereon, while the foot 48 rests directly on the plate 1 (not shown in Figure 2).
  • boss 42 is formed on the foot 44, in the vicinity of the anchor point 50 which ensures the fixing of the gear train bridge 4 on the center bridge 2.
  • the bosses 40 and 42 are formed in the vicinity of the edges respectively of the gear train 4 and of the plate 1.
  • the gear train bridge 4, the center bridge 2 and the plate 1 form three guide pieces mounted and held one on the other in a sandwich form to form a housing between them in which the control member is freely received. 34, and more particularly its free end E.
  • these three guide parts 1, 2 and 4 form in in addition to the rotating supports of at least one mobile 6, 8, or 10 belonging to the horometric means H.
