- Designers of control cam timepieces of this type are regularly faced with certain difficulties. Indeed, the various mechanisms of these timepieces cannot always be arranged in the immediate vicinity of the control cam. As a result, it is often necessary to provide levers of complex shapes, and which extend over a great length, to connect the control cam to the various mechanisms to be switched.
- the patent document EP 1 960 846 B1 in particular describes a control device comprising two column wheels arranged coaxially and which are arranged to be driven by means of the same ratchet.
- the control device described in this prior document is specifically designed to simultaneously control a chronograph mechanism and an hour counter.
- the column wheel which controls the chronograph mechanism is located on the back side of the movement, while the column wheel which controls the hour counter is located on the dial side.
- This prior solution is satisfactory when the mechanisms which must be switched simultaneously are not arranged on the same side of the movement plate.
- its interest is much more limited when the mechanisms to be switched are located at a distance from each other on the same side of the movement.
- An aim of the present invention is to remedy the drawbacks of the prior art which have just been explained.
- the present invention achieves this and other object by providing a control device for watch mechanisms, which is in accordance with claim 1 appended hereto.
- the manually operated mechanism of the control device comprises, on the one hand, a control rocker arranged to cooperate with the external control member so as to pass from a rest position to a tilted position. when the user actuates the external control member and then return to the rest position when the external member is released, and on the other hand, the first and second actuating means carried by the control rocker and arranged to cooperate respectively with the drive means of the two control cams, so as to allow the latter to be driven from one predefined angular position to another by actuating the external control member. Thanks to the characteristics of the invention which have just been listed, it is possible to simultaneously increment two column wheels which are arranged at a distance from one another.
- the two control cams are circular cycle cams, preferably column wheels.
- the two control cams have the same number of hollows and the same number of bumps.
- the control device for watch mechanisms which will now be described in more detail, by way of example, is intended to be integrated into a chronograph watch designed in particular to indicate the fractions of seconds timed using a retrograde hand. associated with fraction of a second counter.
- the chronograph watch of the present example requires the chronograph mechanism and the fractions of a second display device to be switched simultaneously.
- the figure 1 appended shows, by way of example, a chronograph mechanism known as such, which is capable of constituting the chronograph mechanism of the chronograph watch in which the control device of the present example is intended to be integrated.
- a chronograph mechanism known as such, which is capable of constituting the chronograph mechanism of the chronograph watch in which the control device of the present example is intended to be integrated.
- the column wheel (referenced 1) conventionally comprises, in its lower part, a ratchet toothing formed of eighteen saw teeth 2, and in its upper part, six columns 3 regularly spaced around a circle. Note that the ratio between the number of teeth 2 of the ratchet and the number of columns 3 is equal to three, the column wheel therefore being three times.
- the chronograph mechanism shown further comprises a manually operated mechanism comprising a large lever 5 formed of two arms extending on either side of its pivot axis.
- One end (referenced 4) of the rocker 5 is arranged to cooperate with an external control member (not shown), and the other end carries a pawl (not referenced) which is arranged to cooperate with the ratchet of the column wheel 1.
- the push button serving as an external control member
- the large rocker 5 pivots in the direction indicated by the arrow F, driving the column wheel 1 via the pawl.
- the figure 2 illustrates by way of example a retrograde needle display device which is known as such.
- the display device shown is capable of constituting the device for displaying the fractions of a second of the chronograph watch in which the control device of this present example is intended to be integrated.
- this chronograph watch also comprises a mobile fractional second counter which forms part of a cog (not shown) of the chronograph mechanism of the chronograph watch.
- the seconds wheel 8 of this mechanism can, for example, mesh with the pinion of a first intermediate mobile (not shown), and the wheel of this intermediate mobile can mesh with the pinion (not shown) of the fractional second counter mobile.
- the gear ratios of the part of the chronograph train which has just been described can be chosen so that, when the chronograph seconds wheel 8 rotates at the speed of one revolution per minute, the counter mobile of fractions of a second rotates at the speed of one revolution per second, the counter being a counter of tenths of a second.
- the toothing of the chronograph seconds wheel may have 80 teeth
- the pinion and the wheel of the first intermediate set may have 10 and 75 teeth, respectively
- the pinion of the tenths of a second counter set may have 10 teeth.

- a column wheel 135 comprising a ratchet formed by eighteen teeth 137 and six columns 139 erected on the board of the ratchet wheel.
- the ratio between the number of ratchet teeth 137 and the number of columns 139 is equal to the ratio between the number of ratchet teeth 2 and the number of columns 3 in the figure 1 . It is therefore necessary to exert three pressures on the pusher (not shown) so that a column 139 of the column wheel 135 takes the place of the previous one.

- the figure 2 illustrates the display device in its configuration following the stopping of the chronograph. It can be seen that, in this configuration, the spout 141 is lowered between two columns 139, so that the feeler 131 is free to bear against the periphery of the snail 125, the rake 127 thus being in its reading position.
- the toothed sector 129 of the rake meshes with the pinion 123, so that the angular position of the retrograde needle 115 is determined by that of the snail 125.
- the chronograph is then reset to zero by rotating the column wheel 135 by an additional step, the spout 141 is lifted by a new column, which causes the rake 127 to pivot counterclockwise, so that the toothed sector 129 disengages from the pinion 123.
- the retrograde needle 115 is then free to return to position itself above the graduation corresponding to the zero of the scale 119. It will be understood that the column wheel 135 and the column wheel 1 of the chronograph mechanism must be incremented simultaneously.

- the figure 3 also shows a second column wheel 35 comprising a ratchet wheel 37 and six columns 39, and a second jumper 41 biased against the ratchet of column wheel 31 by a second spring 43. It will be understood that the second column wheel therefore comprises also eighteen predefined stable angular positions.
- the figure 3 further illustrates a manually operated mechanism arranged to allow a user to simultaneously increment the two column wheels 15 and 35.
- This mechanism first of all comprises an external control member which is symbolically represented in the form of an arrow ( referenced P). It also comprises a large lever 51 formed of two arms 55, 57 which extend on either side of the pivot axis 53 of the lever 51. The latter is arranged to cooperate with the external control member of the lever. so as to pass from a resting position (shown in the figure 3 ) in a tilted position (not shown) when the user actuates the external control member, and so as to then return to the rest position when the external member is released.

- the figure 3 also shows two leaf springs 27, 47 which are arranged to return the two pawls 25, 45 against the ratchets of the two column wheels 15, 35.
- the external control member consists of a pusher (not shown) which is arranged on the middle part of the chronograph watch.

- the pusher When the user then releases the pusher, the latter is returned to the rest position, so its inner end moves away from the control lever 51. The latter is then free to return to the rest position under the action of its own return spring (not shown).
- the ratchet teeth 17, 37 of the two column wheels are not arranged in the same direction, the column wheel 15 being designed to be incremented in the clockwise direction, while the column wheel 35 is designed to be incremented in the counterclockwise direction.

- the two pawls could both be arranged between one of the column wheels and the pivot axis, all other things being equal, the two column wheels would then turn counterclockwise.
- the leaf spring 47 is mounted on the control lever 51. Indeed, when a pawl is disposed between the column wheel with which it cooperates and the pivot axis of the control lever, it may be advantageous that the spring which returns the pawl against the column wheel is mounted on the control lever 51. It can be seen that, on the other hand, the leaf spring 27 which is arranged to cooperate with the pawl 25 which is biased against the part of the column wheel 15 which is on the side opposite to the axis 53 is mounted on the frame or on a bridge of the timepiece. Finally, it will be specified that, in accordance with the present example, the column wheel 15 of the figure 3 and column wheel 1 of the figure 1 are in fact the same column wheel. In addition, the column wheel 35 of the figure 3 and column wheel 135 of the figure 2 are in fact one and the same column wheel as well.
- control cams of the invention are not necessarily circular cycle cams like column wheels. Indeed, according to other embodiments, the control cams could for example be shuttle cams.

On connait des pièces d'horlogerie qui comportent plusieurs mécanismes commutables qui doivent être commutés simultanément par un utilisateur. Les pièces d'horlogerie de ce type sont souvent équipées d'une came de commande, le plus souvent une roue à colonnes, qui comporte un profil de palpage agencé pour coopérer avec une pluralité de leviers associés chacun à l'un des mécanismes à commuter, et qui comporte également des moyens d'entraînement permettant à l'utilisateur d'actionner la came de commande en rotation.
