Definitions

  • the invention relates to a time-setting mechanism for a timepiece of the type comprising a plate supporting a movement, mechanism comprising a rod which can be operated from the outside of the part by means of a crown, said rod being capable of take at least two notched axial positions, the first neutral and the second active, a sliding pinion coaxial with the rod and sliding on it, said sliding pinion being provided with a teeth shaped to mesh with a time-setting reference, the rod and the sliding pinion being provided respectively with male and female portions of non-circular cross section and fitted one inside the other to drive the sliding pinion in rotation when the rod is rotated and a pull and rocker system for slaving the pinion flowing to the rod and engaging said toothing with said reference when said rod is in the active position.
  • a time-setting mechanism corresponding to the generic definition which has just been given is well known in the state of the art and is shown for example in document CH-A 642 220.
  • the portion not male circular carried by the rod consists of a square which can slide in a correspondingly shaped hole in the sliding pinion.
  • the outside diameter of the sliding pinion is notably greater than the diameter of the rod, which takes up space in thickness.
  • calibers have already been constructed in which the sliding pinion has an outside diameter of the same order of magnitude as the diameter of the rod.
  • a non-circular male portion comprising two dishes engaging in a groove made in the sliding pinion.
  • This solution in addition to the advantage that it brings of reducing the diameter of said pinion, allows a very simple manufacture since the bleeding is carried out by a simple passage of cutter.
  • the end of the rod on the movement side has no sliding pivot in a bearing, the sliding pinion has been guided in an orifice made in the plate.
  • FIG. 1 is a plan view of the time setting device according to the invention.
  • the timepiece comprises a plate 1, a pull tab 2 and rocker 3 assembly linked respectively to a rod 4 and to a sliding pinion 5, a housing 6 for a battery and a gear train 7.
  • the end 8 of the sliding pinion comprises a edge teeth (designated by 9 in Figures 2a and 2b).
  • the sliding pinion meshes with a time-setting reference 10 forming part of the gear train 7.
  • the pull tab 2 pivots about the axis 11. It includes a nose 12 engaged in a groove 13 formed in the rod 4.
  • the pull tab also includes a stud 14 which cooperates with notches 15 and 16 which is provided with the rocker 3.
  • the recess 17 is a housing in which one can press a point to raise the nose 12, which allows extract the rod 4 from the movement.
  • the lever 3 is in the form of a V pivoting at 18.
  • One of the arms 19 of the V is elastic and its end 20 comes to bear on the axis 11 of the pull tab.
  • the other branch 21 of the rocker 3 comprises a first arm 22 intended to hold the zipper in a plane and a second arm 23 in which the notches 15 and 16 are made.
  • the second arm 23 ends in a spout 24 engaged in a groove 25 of the sliding pinion 5.
  • the branch 21 of the rocker is held in place by a lug 26. The puller and the rocker are drawn in position for which the rod is in the pressed-in neutral position.
  • the rod 4 comprises a male portion of non-circular section comprising two dishes 27 engaged in a groove (not visible in FIG. 1) formed in the sliding pinion 5. According to the invention, the rod 4 also comprises at its end opposite to the control crown (not shown) a pivot 28 engaged in a hole 29 in the sliding pinion 5.
  • Figure 1 shows how the pull and tilt mechanism works to control the sliding pinion to the rod, a mechanism known in itself.
  • Figures 2a and 2b are sections along the line II-II of Figure 1.
  • Figure 2a shows in detail the cog 7 mentioned in connection with Figure 1.
  • a pinion 32 integral with the minute wheel drives a timer comprising the wheel 33 and the pinion 34.
  • the pinion 34 in turn drives the hour barrel wheel 35 integral with the hour hand (not shown).
  • the timer wheel is engaged with the time setting reference 10 on which the time setting command can act by the edge teeth 9.
  • the time setting system itself is shown in FIG. 2a when the rod is in the inserted neutral position and in FIG. 2b when this rod is in the active pulled position.
  • the system has a rod 4 actuated by a crown (not shown).
  • a crown In the groove 13 of the rod 4 is engaged the nose 12 of the pull tab 2 (see also Figure 1).
  • the rod continues with a non-circular male portion 40 which has two dishes 27 directed in the direction perpendicular to the drawing.
  • This portion 40 is engaged in a groove 41 formed in the sliding pinion 5.
  • the rod also comprises, beyond the portion 40, a circular pivot 28 which is freely engaged and adapted in a hole 29 which is fitted with the sliding pinion 5.
  • the hole 29 stops at the dotted line referenced 42 from which begins the groove 41.
  • the sliding pinion 5 also comprises a groove 25 in which is engaged the spout 24 of the rocker 3 (see also Figure 1).
  • the rod 4 is engaged on the crown side in a first circular orifice 43 formed in the plate 1.
  • the same is true of the sliding pinion 5 which is guided in a second circular orifice 44 formed in the plate 1.
  • the rod 4 is perfectly guided inside the plate.
  • the rod remains aligned between two support bearings, the first being the orifice 43 guiding and centering the rod proper and the second being the orifice 44 guiding and centering the sliding pinion itself serving as a bearing for the pivot at the end of the rod.
  • Figure 3 is a section along line III-III of Figure 2b. It can be seen that the sliding pinion 5 is adjusted in the orifice 44 drilled in the plate 1. At the rear of the pivot 28 there is a distinction between the non-circular portion 40 carried by the rod 4 and the dishes 27 of this portion and the edges of the groove 41 of the current pinion between which the plates 27 slide.
  • the construction described here by way of example is not limited to the use of two dishes 27 for the rod 4. It could be a square or any other non-circular shape.
  • the diameter of the pivot 28 is shown as being equal to the distance which separates the two dishes. It will be understood that this diameter may be smaller than the distance in question.
