Definitions

  • the present invention relates to a watch movement comprising a three-cycle chronograph mechanism arranged to control a chronograph hand and at least one counter hand so as to turn them on, to stop them, and then to bring them back quickly to their point of contact. departure, at will, by successive pressures on the same push-button.
  • the present invention more specifically relates to such a watch movement comprising a column wheel and in which the successive presses on the push button have the effect of progressively incrementing the angular position of the column wheel.
  • Watch movements are known which correspond to the definition above.
  • the patent document WO 03/040835 in particular, discloses a watch movement provided with a chronograph according to the preamble of appended claim 1.
  • the Figures 1 and 2 annexed reproduce the figures 3 and 8 of this previous document. These figures are side views of this watch movement of the prior art.
  • the figure 1 shows the movement with the chronograph mechanism in the rest position, and the figure 2 is a similar view showing the reset of the chronograph mechanism.
  • a control lever 1 which is pivotally mounted about a pin screwed into the barrel bridge (the pin and the barrel bridge are not shown in the figures, but the pivot axis is indicated by the sign "+" ).
  • An end 1b of the flip-flop is intended to be connected to a single pusher (not shown).
  • the other end of the control lever ends with a pawl 2 in the form of a hook which is provided to cooperate with a ratchet toothing 4a of the column wheel 4.
  • a first spring (not shown) is provided to recall the latch of command 1 in the rest position shown in the figure 1 .
  • a second spring (not shown) is provided to constantly remind the pawl 2 against the ratchet toothing 4a.
  • a jumper spring 3 is also engaged with the ratchet toothing of the column wheel.
  • the end 1b of the flip-flop 1 is connected to the single pusher.
  • the button of the pusher When a user presses the button of the pusher, he pushes the end 1b of the control lever towards the center of the movement.
  • the rocker being pivoted in its center, the displacement of the end 1b towards the center of the movement is accompanied by a displacement in the opposite direction of the pawl 2.
  • the pawl While moving, the pawl hooks a tooth of the ratchet 4a and causes this tooth towards the outside of the movement. In doing so, he turns the column wheel by one step.
  • the rocker is returned to the rest position by the first return spring. During this movement, the hook-shaped pawl 2 slides on the inclined tooth of the ratchet 4a without rotating the column wheel.
  • An object of the present invention is to provide an extremely compact pusher mechanism which allows the use of a small push button with a limited stroke to control the column wheel of the chronograph mechanism of a watch movement.
  • the present invention achieves this goal by providing a watch movement according to the appended claim 1.
  • Figures 11 and 12 represent a column wheel 40 adapted to be integrated in a watch movement according to the present invention
  • the latter is essentially formed of a ratchet 42 and four columns 44 evenly distributed to the circumference of the ratchet.
  • the column wheel further comprises a hub 46 designed to be pivotally mounted about an axis of the chronograph mechanism (not shown in FIG. Figures 11 and 12 ).
  • the figure 11 still contains an arrow referenced R and intended to indicate the direction of rotation of the column wheel 40. It will be noted that, in the present example, it is a clockwise direction.
  • the column wheel further comprises four arms 48 which respectively connect the four columns 44 to the hub 46 of the wheel.
  • the columns 44, the arms 48 and the hub 46 thus form a superstructure which has a rotation symmetry of order 4.
  • the ratchet 42 meanwhile, has 12 teeth spaced 30 ° from each other.
  • the perspective view of the figure 12 allows to clearly visualize the hub 46 and the arms 48 which connect the columns to the hub.
  • the presence of the arms and the hub makes it possible to stiffen the structure of the wheel in general, and the columns in particular. It will be understood that a more rigid column wheel allows operation with a particularly high level of precision.
  • the width of the arms at their narrowest point is considerably smaller than the width of the columns (here the width of a column is defined as the distance separating the leading edge from the trailing edge of this column).
  • the width of the arms 48 is less than half the width of the columns 44. In the present example, the width of an arm is even of the order of one third of the width of a column.
  • This feature of the invention makes it possible to arrange voids 45 in the superstructure of the column wheel. These voids are necessary to allow the beaks of the different flip-flops to dive sufficiently deep between the columns.
  • the hub 46 and the arms 48 have a height less than that of the columns 44.
  • the height of the arms will preferably be between 20% and 60% of the height of the columns.
  • An advantage of the latter feature is that it allows to further extend the stroke of the nose of a lever in diving as in lifting, provided that the lever is mounted high enough to allow the passage of the spout over the arms 48 of the column wheel.
  • the column wheel is entirely manufactured on a topper. A manufacture without recovery on a lathe allows to give the piece a remarkable precision.
  • the figure 11 clearly shows the profile of the columns 40.
  • the profile of the columns generally corresponds to a warped ellipse, or more precisely perhaps, to the profile of an airplane wing.
  • leading edge of the columns referring to the direction of rotation of the column wheel
  • trailing edge of the columns will be trailing edge.
  • the columns also have an outer face (facing the outside of the column wheel) and an inner face (facing the hub 46). The outer face and the inner face meet at the leading edge and at the trailing edge.
  • the profile of the columns draws a circular arc substantially concentric with the column wheel. While at the inner face, the profile of the columns has a larger radius of curvature in the trailing edge region than in the leading edge region (as is the case with an airplane wing). classic).
  • ⁇ is defined by the angle that the inside faces with the outside face of a column in the region of the leading edge, and by ⁇ the angle made by the inside face with the outside face of a column. in the region of the trailing edge.
  • ⁇ is defined by the angle that the inside faces with the outside face of a column in the region of the leading edge, and by ⁇ the angle made by the inside face with the outside face of a column. in the region of the trailing edge.
  • the two angles ⁇ and ⁇ are actually very rounded.
  • the fact that the angle ⁇ is very rounded has the advantage of facilitating the progression of the nozzle of a lever cooperating with the column during operation of the chronograph mechanism.
  • the angle ⁇ the fact that the angle is rounded does not really have any technical effect, and according to one variant, the angle ⁇ could be sharp.
  • the angles ⁇ and ⁇ are respectively 58 degrees and 31 degrees.
  • the angle ⁇ may vary, but it is preferably between 55 and 65 degrees.
  • the angle ⁇ for its part, depends on the number of columns contained in the column wheel, and it will preferably be smaller when the columns are longer. many. However, the angle ⁇ will preferably be between 25 and 35 degrees.
  • the width of a column 44 naturally depends on the number of columns contained in the column wheel 40.
  • the columns of the column wheel are wider than the openings arranged between the columns.
  • FIGS 3 to 8 are bottom-side views of a watch movement according to a particular embodiment of the present invention.
  • the watch movement shown is intended to be integrated into a wristwatch. Under these conditions, the crown-push which is represented at the top in the figures, would actually be at three o'clock if one looked at the dial side of a wristwatch containing the movement. It will therefore be understood that since Figures 3 to 8 are bottom-side views, the "noon" position of the watch is on the right side of the figures, and the hour turn extends counter-clockwise in the figures.
  • the Figures 3 to 8 represent the chronograph mechanism at different phases of a complete cycle of its operation.
  • the chronograph mechanism shown comprises in particular a chronograph wheel 1, a clutch rocker 4 having a spout adapted to cooperate with the column wheel, an oscillating pinion 2 pivoted on a lever clutch 3, and two springs (referenced respectively 5a and 5b).
  • the clutch lever is arranged to pivot in either direction so that it alternately causes the disengagement or engagement of the toothing of the oscillating gear 2 with that of the chronograph wheel 1.
  • the pivoting of the The function of the clutch lever 3 is to stop and restart the chronograph.
  • the oscillating pinion 2 is permanently driven by the second mobile movement gear (not shown). Under these conditions, when the chronograph wheel is engaged with the pinion 2, it is driven, and when the oscillating pinion is disengaged from its toothing, the chronograph wheel is disengaged.
  • the function of the spring 5a is to return the clutch lever, and the oscillating pinion which it bears, against the chronograph wheel.
  • the spring 5b it is arranged to recall the nose of the clutch rocker against the column wheel.
  • the clutch rocker 4 carries, at the end opposite the spout, a pin 6 provided to cooperate with a corresponding end of the clutch lever 3. It can be seen first of all that when the tip of the rocker 4 is lowered between two columns, as shown on the figures 4 and 5 in particular, the pin 6 is spaced from the clutch lever. Under these conditions, nothing prevents the spring 5a meshes the oscillating pinion 2 with the toothing of the chronograph wheel 1.

  • the pusher of the pusher crown 65 is arranged to move axially in the plane of movement when a user actuates the pusher by pressing the button 67 of the pusher crown 65.
  • the pusher thus passes from a rest position (illustrated in the figure 3 particular) to an active position (illustrated in figure 4 especially).
  • the mechanism which, in the example shown, connects the button 67 of the pusher ring 65 to the column wheel 40 comprises a pawl 52, a pawl spring 54, a control lever 56, an intermediate lever 58 and a control spring 60.
  • the pusher ring 65 is disposed at the periphery of the movement, at "3 o'clock".
  • the pusher crown is associated with a winding and setting rod (referenced 71 to the figure 9 ) which extends towards the center of the movement.

  • the control spring 60 is arranged to cooperate with the control rocker 56 so as to return the free end of the latter towards the periphery of the movement. It will be further understood that because of the presence of the pin 57, the action of the spring 60 also has the effect of biasing the lever 58 outward movement. Conversely, when a user pivots the lever 58 by pressing on the pusher 67, the distal end of this lever pushes the pin 57, thus pivoting the control lever 56. Comparing the figures 3 and 4 for example, it can be seen further that the simultaneous pivoting of the intermediate lever 58 and the control lever 56 is accompanied by a sliding of the stud 57 against the distal portion of the intermediate lever. It will be understood that because of this sliding, when the pusher mechanism passes from the rest position to the active position, the lever arm between the pivot 59 of the intermediate lever and the pin 57 is shortened.

It will be understood that the figure 9 is a view of the movement from the bridge side, the plane of the drawing being parallel to that of the movement. The flag formed by the tongue 62 therefore extends in a plane perpendicular to that of the drawing.
