Definitions

  • a mechanism of this type is, for example, described in the theory book of watchmaking from Chs-A. Reymondin et al., Page 232 (Federation of Schools Techniques de Canal, 1998, ISBN 2-940025-10-X).
  • the cam is a column wheel.
  • the clutch member and a rocker bearing a clutch wheel intended to kinematically connect the gear train of finishing of the watch, which runs continuously, with the cog of chronograph, which runs only on demand.
  • the wheel clutch is engaged or out of engagement depending on whether the rocker occupies its first position or its second position.
  • the tip of the rocker is provided with a stopper nose which, in cooperation with the columns of the column wheel, depending on whether it is in gaze of a void or that it rests on a full of the column wheel, defines the first and second positions, under the effect of the rocker spring.
  • the present invention implements means for overcome the disadvantage exposed above.
  • the mechanism is characterized in that the control lever has a lock and the clutch member is provided with a crampon cooperating with the lock when the clutch wheel occupies its first position, all in such a way that the rocker is prevented from moving shock when the clutch wheel is engaged with the cog chronograph.
  • control member comprises a hook secured to the lever.
  • control and a stopper nose arranged to cooperate respectively with the ratchet and with the columns of the column wheel.
  • the hook is arranged so that the lock released the clamp before a column cooperates with the nose.
  • the lever control, the ratchet, the latch and the crampon are arranged so as to that, when the clutch wheel is in its first position, the lever control cooperates with the rocker by means of the lock which is resting against the crampon.
  • the chronograph mechanism according to the invention is further characterized in that the sum of the thicknesses of the bolt and the stud is less than or equal to the length of the arc described by the end of the clutch lever between the positions it occupies when the clutch wheel is in its first or second position.
  • the rocker 16 pivots at its end opposite to that comprising the nose 18 on an eccentric secured to the plate 10, not shown because it is located outside the drawing field.
  • the scale 16 is subjected to a couple of positioning by a rocker spring also arranged outside the drawing field. In the position shown in Figure 1, it is in support against an eccentric 31, the nose 18 being engaged between two columns 40.
  • the control lever 26 pivots on a tenon, and is held in place by a screw 32 fixed in a tapped hole in the post.
  • One of its ends door, pivotally mounted, the control hook 28, while the other end is arranged, in a conventional manner, to cooperate with the push button of ordered. This possible pivoting of the hook 28, combined with the pressure of the hook spring 30, maintaining it in a position allowing it to cooperate with the column wheel 24.
  • the control lever 26 carries a pin 33.
  • an arm 34 is fixed on the upper face of the control lever 26 by means of a screw 35 engaged in a hole made in its middle part.
  • a screw 35 engaged in a hole made in its middle part.
  • One of its ends is provided with a lock 36 arranged to cooperate with the spike 20.
  • the other end forms a stop 37, which comes to bear against the pin 33.
  • Column wheel 24 is made in one piece and consists of a Breguet teeth forming a ratchet 38 and 40 columns arranged perpendicular and concentric to the teeth, the angular pitch columns being twice that of the Breguet teeth. She is positioned by the jumper spring 25 engaged on the Breguet toothing of the ratchet 38. It governs the interaction between the control and clutch devices.
  • the nose 18 of the rocker is engaged in one of the spaces between the columns 40.
  • the wheel clutch 14 is, thus, in its first position and drives the mobile chronograph 22.
  • the latch 36 spans the crampon 20.
  • the length of the arm 26, as well as the shape of the crampon 20 and the latch 36 are chosen so that the arm 34 comes to bear on the rocker 16 by means of the blanks of the crampon 20 and of the latch 36.
  • the arm 34 being integral with the control lever 26, which is positioned by the spring 30, it follows that the lock 36 and the stud 20 are in contact intimate with each other and lock the rocker 16 in its position where the wheel 14 is engaged with the wheel 22, even if a shock tends to move it.
  • control hook 28 and the ratchet 38 do not exactly coincide, the parts having a play two together. More precisely, the control lever 26 must pivot by an angle ⁇ 1 so that the hook 28 traverses the lost path existing between it and the ratchet 38, then by an angle ⁇ 2 so that the column wheel 24 rotates until that a column, identified by the letter a , comes into contact with the nose 18. To ensure optimal operation, the lever 16 must not be set in motion until after the latch 36 has released the clamp 20.
  • the mechanism thus described operates in the following manner.
  • a pressure exerted on the push button rotates the lever 26 clockwise and, with it, the arm 34 and the control hook 28.
  • the hook 28 takes the game of the lost path, then it drives the column wheel 24 until the column 40a comes into contact with the nose 18, lever 26 thus traversing the angle ⁇ .
  • the lock 36, part of the arm 34 is lifts and moves away from the clamp 20, thereby releasing the movement of the rocker clutch 16.
  • the column 40a in contact with the nose 18, raises it, thereby pivoting the clutch lever 16 so that the wheel clutch 14 emerges from the chronograph mobile 22.
  • Column 40a thus acts on the nose 18 of the clutch lever 16 to rotate it in the space left free by the lock 36.
  • the lever begins by taking the game of the lost path, then drives the column wheel 24 with a step of the Breguet teeth, such so that the nose 18 leaves the support of the column 40a and falls into space between two columns.
  • the lever 26 is in a position such that the latch 36 is outside the space traversed by the crampon 20.
  • the clutch lever 16 can therefore pivot freely up to what it meets the eccentric 31, the nose 18 being thus engaged again between two columns 40.
