Definitions

  • a chronograph watch in order to control and manage the various functions of the chronograph, it is known to use a column wheel.
  • the columns of the column wheel conventionally have a cross section often substantially in the form of a truncated triangle (see FIG. figure 1 ).
  • This type of shape makes it possible to manufacture the wheel and the columns in a simple and inexpensive way.
  • the various levers subjected to the action of the columns are subjected to efforts sometimes too important, thus increasing the levels of friction and wear.
  • the level of precision, when implementing the various functions of the chronograph is not always optimal.
  • the characteristics of the invention make it possible to optimize the general mechanical characteristics of the levers cooperating with the columns: for example, a reduction in friction, wear and energy losses, and a better accuracy of the arrangements of parts and functions are obtained. resulting, etc. This results in better management of the chronograph functions.
  • the angle ⁇ is advantageously less than the angle ⁇ of at least 10% and preferably at least 20%. Moreover, the angle ⁇ is preferably between 50 and 53 degrees. It will be understood on the one hand that by choosing a sufficiently salient angle ⁇ ( ⁇ ⁇ 53 °) it is possible to maximize the length of the spout stroke, which allows either to increase the lever lift angle or to increase the length of the lever arm while keeping the same lifting angle. On the other hand, if the angle a is too salient ( ⁇ ⁇ 50 °), the efforts concentrate on the angle ⁇ , which can lead to an undesirable increase in the losses and the force required to actuate a ordered.
  • the ratchet 2 has 12 teeth regularly spaced from each other by 30 °.
  • the column wheel of the present example is a two-stroke column wheel.
  • the present invention naturally applies equally well to three-stroke column wheels.
  • the arrow R on the figure 4 illustrates the direction of rotation of the column wheel 1, ie the clockwise direction.
  • the truncated or trapezoidal triangle shape of the cross section of a column is asymmetrical, with an angle ⁇ less than the angle ⁇ , where the angle ⁇ represents the angle formed between the large base 14 and the leading edge 12, while the angle ⁇ represents the angle formed between the large base 14 and the edge of According to such an arrangement, the leading edge 12 is substantially projected forwardly (in the direction of rotation R) in comparison with a conventional symmetrical arrangement as shown in FIG. figure 1 .
  • the figure 5 shows an example of implementation of a column wheel 1 according to the invention in a chronograph control mechanism.
  • the figure 5 shows a jumper 24 whose spout 25 is provided to cooperate with the teeth of the ratchet 2, a hammer lever 40 seconds / minutes mounted to pivot about an axis 42, a clutch rocker 50 with a spout 51 and finally , a blocking lever 30.
  • the figure 6b is a corresponding view showing the main elements of a chronograph.
  • the blocking lever 30 is integral with a shoe 32 and is arranged to cooperate with the wheel. columns to alternately brake and release the chronograph mobile (referenced 5).
  • the snapshot represented at figure 9 corresponds to the 15 ° position of the column wheel. We see that in this position, the lifting of the hammer beak 41 is accentuated by the action of the column A. The hammer has now completely released the hearts 43. We also see that the clutch rocker tip 51 arrives near the rear area of the large base 14 of the column A. On the other hand, the hammer 40 is releasing the blocker 31, but simultaneously the jammer nose 31 initiates contact with the outer face of the column B .
  • the snapshot represented at figure 10 corresponds to the 20 ° position of the column wheel. We see that in this position, the lifting of the hammer beak 41 is almost completed. It is also seen that the clutch rocker nose 51 is about to plunge. On the other hand, the blocker beak 31 is now well against the large base 14 of the column B.
  • the snapshot represented at figure 12 corresponds to the 30 ° position of the column wheel. It can be seen that in this position, the clutch lever 51 is always lowered between two columns and the gear 28 now meshes with the chronograph mobile which is thus engaged, which corresponds to the start ("start") of the chronograph.
  • the blocker beak 31 remains in abutment against the large base 14 of the column B.
